Sexing a three-week-old Delaware chick can be challenging, but there are some methods you can try. One is to look at their feathers: males tend to have longer wing feathers than females, and males of most breeds will start producing long, pointed saddle, hackle, and sickle feathers around this time. Another method is to observe their behaviour: males tend to be more active and bold, while females may be more docile. You can also look at their combs and wattles: in some breeds, males may develop larger combs and wattles faster than females. However, it's important to note that these methods may not be 100% accurate, and it can be difficult to determine the sex of chicks with certainty until they are older.

Wing feather comparison
To use this method, the father of the chicks must be pure for rapid feathering, and the mother must be slow. The chicks must be examined when they are only 2-3 days old at most. In this case, the male chicks will have slow feathering, with their primary and covert feathers being the same length. In contrast, the female chicks will have longer primary feathers and shorter covert feathers.
It is important to note that this method only works if the parents carry the right genetics for this trait; otherwise, it is random. Additionally, it can only be used with mixed-breed chicks, as purebred chicks will not carry the necessary genes.
Another method that utilizes wing feathers is specific to commercial white hybrid egg layers marketed under certain brands. In these breeds, day-old female chicks exhibit fast feathering, with longer and thicker primary wing feathers compared to their covert feathers. On the other hand, day-old male chicks show slow feathering, with primary and covert feathers of similar length and thickness.

Colour genetics
The colour genetics of chicks is a fascinating area of poultry science. The sex of a chick is determined by its chromosomes, with males carrying two Z chromosomes and females carrying a Z and a W chromosome. This genetic makeup can be used to predict the colour of a chick's down at birth, through a process known as colour sexing or colour genetics.
Colour sexing involves crossing two different breeds of chickens, utilising sex-link genes, to produce offspring with distinct colour variations based on their sex. For example, mating a Rhode Island Red male with a Rhode Island White female will result in male chicks with yellow or white down and female chicks with brown down. The most common sex-link crosses are red sex links, which account for nearly half of the global chicken population.
In addition to the classic gold and silver colour patterns, other colour variations can be achieved through specific breed crossings. For instance, crossing a Golden Campine male with a Silver Campine female will produce male chicks with whitish, grey, or pale brown down, while female chicks will exhibit reddish-brown or buff down. Similarly, using a Black Red male, such as a Brown Leghorn, with silver pattern females will yield male chicks with a lighter, greyish colour, especially on their dorsal stripes, and female chicks with darker stripes.
While colour sexing is a useful tool, it is important to note that there are exceptions and variations within each breed. For example, female day-old chicks can exhibit a range of colours, from uniformly brown to brown with light stripes or a lighter body. Male day-old chicks may also show slight brown stripes or have yellow or white down. These variations emphasise the importance of considering breed-specific characteristics when utilising colour genetics for sexing chicks.
Beyond colour sexing, autosexing breeds are another method for determining the sex of chicks based on genetic colour markings at birth. Autosexing breeds are straightbred varieties where males and females can be bred together while still producing offspring with predictable sex-based colour characteristics. Examples include barred and cuckoo breeds, where males are paler with irregular head spots, and females are darker with narrow head spots and yellow toes.

Tail sexing
When it comes to tail sexing, one of the indicators to look out for is the growth of tail feathers. After about one week of age, many female chicks will start growing tail feathers, while male chicks will still have little or no tail feathers. This difference in tail feather growth can be an early indicator of gender. However, it is important to note that this method may not always be accurate, as some male chicks can feather in just as quickly as females.
Another aspect to consider during tail sexing is the colour and markings of the tail feathers. In some breeds, such as the Delaware chicks, males tend to have more black markings in their wings and necks, while females may have white or lighter-coloured feathers. Additionally, males may exhibit speckling or "smut" down their backs between the shoulders, which is considered a male trait, although it is not always a definitive indicator.
It is worth mentioning that tail sexing is often used in conjunction with other methods, such as wing feather sexing and comb sexing, to increase the accuracy of gender determination. The most reliable way to determine the gender of a chick is to wait until they are older, typically around 6 weeks old, and observe their physical features and behaviours.
By combining tail sexing with other methods and allowing the chick to mature, you can increase the likelihood of accurately determining the gender of a 3-week-old Delaware chick. However, it is important to approach these methods with caution, as there may still be exceptions and variations among individual chicks.

Behavioural differences
Male chicks (cockerels) tend to be bolder and more active than females. They are less likely to scatter when startled and will stand erect and give a warning chirp. They may also rush to the feed dish and make slight cooing sounds. This is a sign of their instinct to care for the females. When startled, male chicks will also ruffle their down feathers and stand erect when looking at another male chick.
Females (pullets) are more likely to hide in corners and crouch down and remain silent when startled. They may also squat and hold their wings out to the side in the mating position when picked up.
It is important to note that these are general behaviours, and there will always be exceptions. For example, some female chicks may exhibit bold behaviour, and some male chicks may be more reserved.
In addition to behaviour, there are other ways to sex a chick. These include vent sexing, feather growth patterns, and colour differences, although these methods may not be accurate for all breeds. For instance, Delaware hens have black in their wings, while males have a lot of black. Genetic testing is also an option for those who want certainty.

Combs and wattles
While there is no simple way to determine the sex of a chick, one method is to examine their combs and wattles. In general, roosters' combs turn red earlier than hens' combs. Roosters are born with small yellow combs and no wattles, while hens have larger combs. However, it is important to note that not all breeds exhibit these characteristics, and the size of combs and wattles can vary among breeds.
As chicks grow older, their combs and wattles become more noticeable. By the time they are a few weeks old, the comb of a young rooster will typically be larger and pinker than that of a hen. Male chicks' wattles also tend to grow faster, longer, and brighter than those of female chicks. Therefore, if you notice that a chick is developing wattles at a young age, it is likely a male.
When comparing two chicks of the same age and breed, you can more accurately determine their gender by examining their combs and wattles. However, it is important to note that this method may not work with pea comb breeds, which have flat and bumpy rose combs instead of tall and floppy regular combs.
While examining combs and wattles can provide some indication of a chick's gender, it is not always a foolproof method. For example, the size and colour of combs and wattles can vary among individual chickens, and some hens may have larger combs than expected. Therefore, it is recommended to combine this method with other sexing techniques, such as observing behaviour, wing feathers, and vent sexing, to increase the accuracy of gender determination in baby chicks.

Frequently asked questions
You can try to sex a 3-week-old Delaware chick by observing its behaviour and physical characteristics. Males tend to be more active and bold, while females are more relaxed. Males may also have longer wing feathers than females. However, it is important to note that these methods are not always accurate.
In some breeds, male chicks will have an even row of wing feathers, while females will have some long and some short, alternating feathers. However, this method should be used within the first few days of hatching, as feather growth will equalize for both sexes after that.
In some breeds, male chicks will have whitish, grey, or pale brown down, while female chicks will have reddish-brown or buff down. However, this method only works for specific breed crosses.
The most accurate way to sex a chick is through genetic testing or DNA testing. Vent sexing, which involves examining the chick's vent, is also considered precise, but it is not recommended for amateurs and is most effective with day-old chicks.
