I recently traded for an 8 month old Barred Rock, and I'm worried about her. I've had her for a week, and since I got her, she's had a red, completely naked butt (No fuzzy feathers at all), no tail, no flight feathers, and the last segment of her wings is naked. The last wing joint is also naked. My birds hate her and bully her when they're confined to the run (maybe an hour every day), and Stop-Pick isn't working at all. Also, her butt is dripping white pasty poop, no matter how many baths she gets, and it drips a clear liquid too. No eggs so far, but if she's moulting I wouldn't expect it. Is this a normal moult?? The previous owner said he'd bring me a different bird if it wasn't working out, should send her back? She's incredibly friendly but I don't want a sick bird! She's been eating grower and lots of fruits and veggies, and I add a tiny bit of apple cider vinegar to their water. She dust bathes regularly and naps in the sun near another bird. It's been around 60-70 here lately. Help?
