I just got a new batch of chicks, mixing day-old leghorns, rocks, and others (and 2 turkeys) with week-old Banties. The chicks are now itching like crazy, and a couple of the Banties look downright haggard, missing feathers and really mottled-looking. I haven't noticed any of the others picking on them. They all are itching and preening themselves and picking something off each other, although I can't see what it is. I think they may have mites. They guy at the hatchery told me my straw may have harbored them, so I'm going to try removing them and cleaning their coop really well, then putting them back in on paper towels, which I read may help both with seeing the mites and removing them, if you change the towels often. Also, two of the Banties have what I thought was just the normal poop clingons on their butts, but when I went to remove it, it wouldn't come off, even with warm water, like it's a part of her skin protruding or her insides coming out her butt or something that's now covered in poop. I fed them yogurt this morning (free choice) in hopes of correcting any digestive issues they may have. I tried to attach a photo, but don't know if it worked. I would appreciate comments/advice about either of these issues. Thank you!
