Hi there again folks, I have a 2-year-old ameraucana who seems to be missing feathers around her vent region. I have yet to be able to catch her to check it out, she's full of energy and we have lately nicknamed her "anger bird" as she's quite belligerent to three birds we got in about a month ago (but not actually injuring any of them). She's the bossy one I suppose. Anyways, she's eating, running around, laying and doing everything else just fine and dandy. I don't remember her being so bossy when we first got her at all. I noticed the "bald spot" on her butt about 2 or 3 weeks ago. There aren't any feathers laying about that I've seen in any quantity so they aren't falling out rapidly. I just recently noticed that the spot is larger, about the size of a lemon in diameter. What could be causing this?
