A couple weeks ago my friend hatched a batch of frizzle chicks and this one turned out bald. During the first week of watching her at first I thought she was getting picked on by others but now I can see that is not the case. She is probably around 6 weeks old by now and has still not grown any feathers in certain spots like the top of her wing and her underside. I've never seen anything like this so I looked up some similar cases that pointed to a hormonal imbalance. She is a little bit smaller than all the other chicks in her batch but other than that she seems normal in her activity. She is bright-eyed and active. I don't think this is something that's fixable, but I'm worried about the other girls picking on the exposed skin and exposure to the elements. I'm not really sure what to do so if anyone has any ideas on what this is and how I can help that would be great.
