Egghead Jr. is a large-headed and very intelligent baby chick and appeared in several shorts with bumptious Foghorn Leghorn (also a character directed by McKimson and voiced by Mel Blanc). The only child of Miss Prissy , a widow hen, Egghead Jr. was bookish and never talked (though he mumbled when he counted playing hide-and-seek with Foghorn ...
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.
The first-hatched chick is a reference to which parents discriminate between later-hatched chicks. Chicks that do not match the imprinted cues are then recognized as parasite chicks and are rejected. [8] Chick recognition reduces the costs associated with parasitism, and coots are one of only three bird species in which this behavior has evolved.
The chick will roll the other eggs out of the nest by pushing them with its back over the edge. If the host's eggs hatch before the cuckoo's, the cuckoo chick will push the other chicks out of the nest in a similar way. At 14 days old, the common cuckoo chick is about three times the size of an adult Eurasian reed warbler.

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 ]
The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds.

A pair of welcome swallow chicks, Hirundo neoxena, taken the day after they fledged. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling .
