I have a few 6 week old chicks that are not developing feathers on their backs. Some very helpful people suggested I post pictures of them here so all of you well informed of chicken breeds can help us out with what breed they are and info about the lack of feathers. We are new to posting on this forum but have gotten helpful info from it since we bought these (our first ever) chicks this spring. My husband and I have 4 kids - 7, 5, 3 & 1 and we all would love to know what breed of chickens we have. We bought a "special assorted bargain" and are a little overwhelmed with how many different kinds of chickens there are. Prior to this past April, we seriously thought that a chicken was a chicken and that's about as far as it goes... The only ones we've made an id on are the enormous white leghorn roosters. The chick on the left is one with a bare back, he is black with feather legs. There are two like this almost identical. The other pretty girl is Penny, one of my daughter's favorties. She would love to know what type it is. Two other bare backs, one I think is a cockerel, the other I'm not sure. This is Jack. My son named him and it is his favorite. Again, we'd love to know what breed he is. The little cockerel in the middle who is kind of buried has almost no feathers on his back and his wing feathers are really short. There is another cockerel that is exactly the same, we cannot tell them apart. The hatchery called these tophat varieties, we call them feather heads. Is tophat the breed or is there a more specific breed name for these? Also would like to know the gender, neither has a very developed comb yet so we are guessing hens but weren't sure. Thanks in advance!
