My wife and I recently bought 9 new chicks - our first ever (mostly Rhode Island Reds, with a couple RI "Whites" as well). They seem happy and healthy, but last night we noticed what looked like a pasty butt on one of the chicks, only it's about half an inch ABOVE its butt. We wiped it with a wet paper towel and rubbed it a little bit hoping it would just wash off, but so far no luck. Not sure if this is a growth, an infection, a parasite, or nothing to be worried about. I'm afraid I don't have a great pic, I'll try to take more at home this evening: Thanks for your help!
