Does anyone know what breed these four chicks are I got them from tractor supply a while ago and they were in the bantam tank. But I had hatched two chickens about a month or longer before I got them and these were a few days old when I got them and they are bigger than the ones I hatched so I was think maybe some kind of Cornish but as huge as there legs are and the size they are at there age I was also considering black jersey Giants but I don't think they are those. The two black ones are my main concern but I would also like to know what breed the other two are. Plus can anyone tell me the gender of them also I think they are all roosters but I just can't imagine them all roosters. I will get the other pics of the other two here in a bit thanks in advance.
