Delayed-feathering in chickens is a genetically determined delay in the first weeks of feather growing, which occurs normally among the chicks of many chicken breeds and no longer manifests itself once the chicken completes adult plumage.
Very precocial birds can be ready to leave the nest in a short period of time following hatching (e.g. 24 hours). Many precocial chicks are not independent in thermoregulation (the ability to regulate their body temperatures), and they depend on the attending parent(s) to brood them with body heat for a short time. Precocial birds find their ...
Vent sexing in Wenchang, Hainan, China (2014). Vent sexing, also known simply as venting, involves squeezing the feces out of the chick, which opens up the chick's anal vent (called a cloaca) slightly, allowing the chicken sexer to see if the chick has a small "bump", which would indicate that the chick is a male.
Castrated males can go broody with baby chicks, [8] showing that broodiness is not limited to females, however, castrated males do not incubate eggs. Contrary to common opinion, the temperature of broody hens barely differs from that of laying hens. [8] Broody hens pluck feathers from their chest, using them to cover the eggs.

One day after hatching, chicks will weigh 105 to 115 g (3.7 to 4.1 oz), with an average of 110.6 g (3.90 oz). [ 63 ] [ 64 ] In the first 10 days, chicks mainly lie down on the nest substrate. [ 62 ] The eagles are capable of preening on their second day but are continually thermoregulated via brooding by their parents until around 20 days. [ 1 ]
