Most chicken meat in grocery stores comes from broiler chickens that are typically slaughtered between five and seven weeks old. Broilers are bred to grow rapidly, reaching slaughter weight between 35 and 50 days. Their feed is designed for fast growth, not longevity, and they grow 3-4 times faster than egg-laying or heritage breed chickens. This rapid growth can lead to health issues such as heart disorders and leg problems. While broilers are the most common, some brands offer meat from older roaster chickens, typically slaughtered at 9-12 weeks old. These older chickens have more developed fat for moisture and flavour and are firmer in texture.

What You'll Learn
Grocery store chicken is typically 5-7 weeks old
The age of chicken sold in grocery stores varies, but it is typically between five and seven weeks old. This is because most store-bought chicken comes from broilers, which are chickens that reach slaughter weight between 35 and 50 days of age. In just five weeks, broiler chicks can weigh 2 kilograms (over 4 pounds), as they are fed a diet designed for fast, lean growth rather than longevity.
The age of the chicken you buy can influence the flavour and texture of the meat. Older chickens tend to be more juicy and flavourful, as they have had more time to develop fat for moisture and flavour. They also have more time to develop muscle fibres, which leads to less variation in texture. However, younger chickens are cheaper to produce, as they reach slaughter weight more quickly, and are therefore more readily available in grocery stores.
Chicken in grocery stores can sometimes be older, with some brands offering meat from roaster chickens that are typically 9-12 weeks old at slaughter. These older chickens have a more robust flavour and texture, but they make up a very small share of commercially raised chickens due to their higher production costs.
It is worth noting that the age of the chicken is not usually listed on the packaging in stores. However, there are some voluntary labels that can help you find meat from slightly older birds, such as free-range, pasture-raised, and air-chilled designations. These chickens tend to be more expensive, as raising them outdoors for longer incurs higher production costs.
Chicken typically has a shelf life of 15-17 days from the slaughter date, so the chicken you buy from a grocery store is unlikely to be much older than 7 weeks old, even if it is not fresh.

Broiler chickens are the most common
The young age of broiler chickens has several implications for the meat they produce. Firstly, because they have had less time to develop bones, organs, and a strong immune system, their meat tends to be less juicy and flavourful compared to older chickens. Secondly, their rapid growth can lead to more variation in texture as the muscle fibres don't have sufficient time to fully develop. Additionally, the meat from younger chickens is generally less nutritious as they have had less time to absorb vitamins and minerals from their feed.
Despite these potential drawbacks, the use of broiler chickens in the grocery industry is prevalent due to their low cost and efficiency. Raising chickens that reach slaughter weight quickly is more profitable for producers, as it reduces production costs associated with longer feeding times and outdoor space requirements. While some brands offer meat from older roaster chickens, typically slaughtered at 9 to 12 weeks of age, these birds make up a very small share of commercially raised chickens due to the higher production costs.
Consumers who seek meat from older chickens can look for certain labels and designations. Free-range, pasture-raised, and air-chilled chickens are more likely to be older at slaughter. Additionally, comparing weights, inspecting texture, and considering price points can help identify meat from older birds, as they tend to yield larger pieces with firmer meat at a higher cost. However, it is important to note that chicken packaging rarely lists the slaughter age, so consumers must rely on other indicators to gauge the relative age of the birds.

Older chickens have more flavour
Most chickens sold in grocery stores are about 6 to 8 weeks old or younger. The younger the animal, the more tender the meat. These younger chickens can be cooked in a variety of ways, including frying, baking, grilling, broiling, stewing, or using a crockpot, and the meat will still be tender.
However, older chickens, those a year or two old, can also be used for meat. While they may be scrawnier and their meat is tougher, they usually have more fat, making them tastier. Older chickens have a stronger, more concentrated chicken flavour that can be almost gamey or beefy. They are best suited for slow-cooking methods, such as stewing or slow-baking, which help to tenderise the meat and enhance the flavour.
For example, one person described preparing an old hen for a tagine, which required longer cooking but resulted in a superior taste with a tender texture. The same user also recommended using older chickens for chicken noodle soup or similar dishes.
Another individual shared their experience with processing older roosters and shared that these birds were scrawnier than expected, emphasising the importance of using suitable cooking methods for older chickens.
When cooking older chickens, it's important to use low heat and moist cooking techniques to prevent the meat from drying out. Slow-cooking methods, such as stewing or using a crockpot, can help create tender and flavourful meat. Additionally, soaking the chicken in buttermilk overnight before cooking can also enhance the results.

Chicken shelf life is 15-17 days from slaughter
The shelf life of chicken, from the date of slaughter to the grocery store shelf, is typically 15-17 days. This is to ensure that the meat remains fresh and safe for consumption. During this time, the chicken is processed, packaged, and transported from the processing plant to the grocery store.
Proper handling and storage of chicken are crucial to maintaining its quality and safety within this shelf life. The chicken is usually processed within a few days of slaughter, and then packaged and stored under controlled temperatures to inhibit bacterial growth and maintain freshness.
In the United States, the Department of Agriculture (USDA) sets guidelines for the safe handling and storage of poultry products, including chicken. These guidelines dictate the sanitary conditions in processing plants, transportation, and storage facilities to ensure the meat remains wholesome and fit for consumption.
Once the chicken reaches the grocery store, it is important for retailers to adhere to proper storage practices. Raw chicken should be kept refrigerated at all times, with a typical shelf life of 1 to 2 days in the refrigerator. Some retailers may freeze the chicken to extend its shelf life, allowing it to be safely stored for up to 9 months for chicken pieces and up to 1 year for a whole chicken.
It is worth noting that the shelf life of chicken can vary depending on various factors, including the initial quality of the meat, the efficiency of the supply chain, and the storage conditions. Proper labeling and adherence to "best before" dates are crucial to ensuring that consumers use the chicken within its safe consumption period.

Check for organic or free-range labels for older birds
When it comes to buying chicken, the labels can be confusing and may not mean what consumers think they mean. The term "organic" is regulated by the USDA and prohibits the use of the term on packaging unless the product has been produced in accordance with its rules. To be labelled "organic", the chicken must have been fed a certified organic, vegetarian feed that does not include any genetically modified ingredients or toxic synthetic pesticides. This does not, however, guarantee anything about the chickens' quality of life.
"Free-range" is a less strictly defined term, with no precise federal government definition. The USDA approves the use of the term on a case-by-case basis, generally permitting its use if chickens have access to the outdoors for at least some part of the day. There are no standards for the size of the outdoor area or the door to the outside, and inspections are not required to use this label. In the UK, the Farms Director at Daylesford Organic has stated that "the term free-range does not guarantee high welfare".
In addition to these labels, there are a number of third-party organizations that work with poultry producers to establish consensus on issues that matter to consumers. For example, the National Chicken Council's definition of humane treatment has been used as a standard for the "humanely raised" label in certain programs.
When buying organic or free-range chicken, it is worth considering the following:
- Visit the farm: If possible, take the extra step and visit the farm where your food comes from. If the farm is not open to the public, you might want to reconsider.
- Check for "humane organic" labels: Look for labels such as humanely raised or "humane organic", which indicate that the chicken has been treated in accordance with certain welfare standards.
- Be aware of loopholes: Be aware that loopholes exist in the meat-labelling industry, allowing factory farms to use organic and free-range labels while raising chickens in less than ideal conditions.
- Check for "No Antibiotics Ever": If you want to avoid antibiotics, look for the "No Antibiotics Ever" label. This indicates that the chicken has not been treated with antibiotics, as those that have been treated will have a different designation.
- Check for "Non-GMO": If you want to avoid genetically modified ingredients, look for the Non-GMO Project Verified label, which requires verification and means that the chicken's feed is comprised of less than 0.9% genetically modified crops.
