Is the way a chick feathers out any indication of sex? I have chicks that are the same breed, hatched on the same day. Some have their wings filling in rapidly whilel the others have just a tiny bit of feathering on the tips of their wings. I noticed some are also getting their tail feathers first as well. These are all a week old. Thanks for any help, just curious. It will be interesting to keep tabs on them and see how it plays out.
