Okay, weird question but maybe its common so I don't know. I'm going to ask.. The 1st day my chicks arrived in the mail they were all peeping and adapting to their brooder well. Eating and drinking. I kept noticing one of them looked like it had a really big black hair stuck to it. I initially thought it was just something stuck to it from it's litter it arrived in. I picked it up gently pulling on it expecting it to just break loose from the fluff. Instead a little bit of mucus, blood, and tissue came out of the end of it when I pulled it out. The chick didn't seem to notice and has been fine since (7 or so days now) but I am just curious what that could have been?
