thats a cock! as far as what breed, if you ordered it from a hatchery or something to that nature, it probably is a golden comet or sex link. if just picked up any old where, then it is diffently a barn yard mix with comet sex link or road island red. as far as easter egger, if you mean amercana, there is no way. cock for sure though, what ever the breed, the chick is young and is just starting to get cock feathers in his tail. if its a hen it will have some of the nicest tail feathers i have ever seen.
