Chicken Housing: Starter Growers Explained

what is a starter grower in a chicken house

Chickens have different nutritional requirements at various stages of their development, and chicken feed is formulated to meet these needs. Chicken feed comes in three types: starter feed, grower feed, and layer feed. Starter feed is for chicks and is high in protein to meet the dietary requirements of baby chicks. Grower feed is for adolescent chickens and has a lower protein content than starter feed. The transition from starter feed to grower feed typically occurs when chicks are between 6 and 8 weeks old.

Layer feed Contains a balance of protein, calcium, and other important vitamins and minerals to promote health and enhanced egg quality and production
Starter feed duration Until the chick is 6-8 weeks old
Grower feed duration From 6-8 weeks until 18-20 weeks
Layer feed duration After 18-20 weeks or when the chicken starts laying eggs

Starter feed is crucial for bone health and immunity

Chickens go through three primary growth phases: the starter phase, the grower phase, and the layer phase. The starter phase begins at hatch and lasts until the chick is 3-8 weeks old. During this critical period, chicks must develop their digestive tracts and learn to digest food. They also need to develop their immune systems and grow their feathers, which are essential for temperature regulation.

The immature digestive system of a newly hatched chick is particularly sensitive to anti-nutritional factors (ANFs) found in untreated soy protein. ANFs negatively impact protein absorption, hindering the chick's potential for healthy growth. Optimized starter feeds, such as HP AviStart, address this issue by reducing ANFs while maintaining the nutritious protein components intact.

Additionally, the digestibility of the feed is crucial for chicks. Their digestive tracts and immune systems are highly immature at hatching, so a feed that is easy to digest ensures proper nutrient absorption. Without adequate nutrition, chicks become more vulnerable to pathogenic bacteria and viruses, such as Salmonella and Campylobacter.

By providing starter feed, you ensure that your chicks receive the protein, vitamins, amino acids, and minerals they need to develop strong bones and robust immune systems. This foundation sets the stage for their continued growth and development as they transition to the grower phase and eventually become laying hens.

Grower feed supports healthy development

Chickens go through three primary growth phases: the starter phase, the grower phase, and the layer phase. The type of feed they require changes over their lifetime.

Starter feed is fed to chicks after they hatch until they are around six weeks old. This feed is protein-dense, typically containing 18-24% protein, and is designed to meet the dietary requirements of baby chicks. It supports bone health and immunity, helping chicks to develop their digestive tracts and establish their immune function.

Feeding growing chicks too much protein can cause kidney or liver problems later in life, so it is important to make the switch to grower feed at the appropriate time. Grower feed helps to ensure that chicks develop into thriving and healthy adult birds.

Chicken feed comes in various forms, such as medicated or unmedicated, and textures, such as pellets, to suit the needs of different chickens and chicken keepers.

Layer feed helps hens lay strong, healthy eggs

Chickens have three primary growth phases: the starter phase, the grower phase, and the layer phase. The first weeks of a chick's life are known as the starter phase, during which chicks develop their digestive tracts, establish their immune functions, and grow feathers for temperature regulation.

The grower phase comes next, and it is important to make the switch from starter feed to grower feed, as the former contains more protein and calcium, which can cause kidney or liver problems in growing pullets. Layer feed is designed to meet the needs of mature laying hens and typically contains a balance of protein, calcium, and other important vitamins and minerals that promote health and enhanced egg quality and production.

Feeding chickens table scraps as treats is common, but excessive scraps and greens can adversely affect egg production. Scraps with strong flavors, such as onions, should not be fed to laying hens, as eggs might take on those flavors. A balanced diet is necessary for optimal growth and production, and commercial feeds from reliable feed stores have all the nutrients in the right proportions.

Meatbird feed encourages rapid growth and weight gain

Chickens go through three primary growth phases: the starter phase, the grower phase, and the layer phase. The starter phase begins immediately after a chick hatches and lasts until they are between three and six weeks old. During this time, chicks develop their digestive tracts and begin to digest food. They also start to develop their immune function and grow feathers, which are crucial for temperature regulation.

Meatbird feed is designed to encourage rapid growth and weight gain in chickens raised for meat, also known as meat birds or broiler chickens. Meatbirds grow at an incredible rate and require a lot of energy, protein, and amino acids to build muscle mass. A meatbird feed should be high in crude protein and amino acids to support this rapid development. A diet containing around 22% protein can help meatbirds reach their ideal market weight in as little as 6 to 10 weeks.

Meatbird feeds, such as Nutrena NatureWise® Meatbird Feed, contain a blend of essential oils distilled from oregano, thyme, rosemary, and star anise. These essential oils promote digestion, growth, and a healthy immune system. Additionally, meatbird feeds may include prebiotics, probiotics, and yeast cultures that support digestion and overall chick health. It is important to note that meatbird feeds are specifically formulated for meat chickens and should not be fed to laying hens, as the excess protein can be detrimental to their health.

To maximize the potential of meatbird feed, it is recommended to provide it as the sole ration from hatch to finish. For the first three days, free feed the chicks, and then implement a 12-hours-on/12-hours-off feed rotation to prevent overeating. Always ensure that clean, fresh water is available, and regularly clean feeders and waterers.

Chicken scratch is a great energy source and supplement

Chicken scratch can be a great way to provide supplemental energy to your flock, but it's important to remember that it should not be their main source of nutrition. Their primary diet should be a nutritionally balanced feed mix. Scratch can be fed once or twice a week in the late afternoon when chickens are winding down. This timing allows them to enjoy their evening meal without filling up on too much scratch.

During the winter, chicken scratch can help hens stay warm. Feeding scratch before dusk on cold days provides a thermic effect, creating heat as it's digested. This is especially beneficial on long winter nights. Additionally, providing scratch in the form of a flock block or inside a toy that requires more effort to access the food can promote activity and help fight boredom during the colder months when hens are more sedentary.

Chicken scratch can also be a good way to offer protein to your chickens. For example, amaranth can be added to chicken scratch to increase protein energy. Small meat scraps are another option for providing supplemental protein to your flock.

Chicken scratch is a great way to supplement your chickens' diet with additional energy and nutrients. However, it's important to monitor their health and condition, ensuring that they do not consume too much scratch, as this can lead to digestive problems and unwanted weight gain.

Frequently asked questions

Starter and grower are two of the three primary growth phases that most backyard chickens go through, with the third being the layer phase. Chickens have different nutritional needs at each stage of their growth. Starter feed is fed to chicks after they hatch until they are about six to eight weeks old. Grower feed is for chickens between 6 and 20 weeks old.

Starter feed is protein-dense (usually 20-24% protein) and designed to meet the dietary requirements of baby chicks. It should be filled with complete proteins, amino acids, vitamins, and minerals to establish and support bone health and immunity.

Grower feed contains less protein than starter feed (16-18%) and less calcium than typical layer feed varieties. It supports continued growth and helps build strong bones until chickens reach maturity.

Layer feed is designed to meet the nutritional requirements for chickens that are old enough to lay eggs. It contains a balance of protein, calcium, and other important vitamins and minerals that promote health and enhanced egg quality and production.
