I got my first batch of chicks yesterday, never had chickens before. My favorite chick, Mumble, has an injury/bulge right below its eye that I've been treating, and also I've noticed a lot of poop stuck to its bottom. I drained the bubble on its face and applied neosporin (the bulge was affecting the eye and mouth). What should I do about its bottom? He/she is the biggest of all the chicks, but the bulge on its face was affecting the mouth so it could have limited the feed intake. I just want my chicks to be happy and healthy.
