Hi there, This may sound odd, but... should I gently trim the butt fluff of one of my chickens that tends to get poop on the fluff below her vent? It doesn't exactly look like pasty butt to me, and she has no problems eliminating. Being nervous, I cleaned her vent area when she was one week old. This is what it looked like two days ago: Should I do anything about it? She's 2.5 weeks old. Thanks!
