I need help with figuring out what is wrong with my chick. It is only a few weeks old is still very active and very fast it was hard to catch it. It has no discharge from the eyes or nose. I have been giving it fresh water daily and medicated chick feed. I did kill three black widows in the brooder area over the last two days. No other chick shows any signs of swelling there is little fuzzy left in the back of the neck but there are hard pin quills coming in . I was wondering if maybe it got bit by a spider or might have an ingrown feather.
Here are a couple of photos of it the swelling is on the back of the neck and between its wings on its back too
