So my fiance and I decided to raise chickens. Our chicks are about 3 weeks old and all starting to grow in feathers. Our smallest, Poof, has a bald spot on her head. At first I thought it was just her feathers coming in, but this morning we noticed its also red/raw? Most of what I found suggests she may be getting pecked unfairly, but we honestly haven't observed any aggressive pecking behaviors with our flock. We noticed her head doesn't fit very easily into the feeder holes and is probably rubbing against the inside edge when she pulls her head out. We bent to sharp edge inward on all the holes to help, but I don't think it's a solution that's going to last very long as she gets bigger. This is our first brooding so despite reading everything I can get my hands on, I still feel like we have no idea what we're doing. I remember being worried after we brought her home that her crest might eventually become a problem with the feeder. Is there some secret step I missed where we are supposed to buy a different feeder once their feathers start coming in? Thank you in advance for any help you can offer. I want to give Poof what she needs to grow up to be a successful hen.
