Hi, I always find so much useful information here, just when I need it! Hoping you can help me. I have 10 pullets that I incubated and they are now 7 months old. One of them was scratching and giving her feathers a shake today and I noticed that she had a little white bump on her skin - in the middle of her back where her tail feathers started. I didn't know if it was lice, so I took a close look and it's one solid, smooth bump, not a "bumpy" bump like lice would be. Little feathers were growing from it. I was curious about it so I picked up another chicken who was nearby and she too has the bump. So, what is the bump? Is it a pest or is it normal? Thanks for any help you can give.
