Hello! My name's Tara and I'm new here. Today I picked up six adult button quail from a small farm. I used to raise buttons but gave it up when I went to college. I have a house now, and had been thinking about purchasing more this spring. I started looking for people in my area raising them, found a farmer who wanted to get rid of the last six of his right away, so we made a deal and I came home with the buttons, 3 male, 3 female. I can't tell the hens from the roosters quite yet - they were in with larger birds and are all quite badly featherpecked. There are two pied/tuxedo, one white, one cinnamon, and what look like two normal coloured browns. When I got them home, I tried separating them into pairs by colours. The button who's most featherpecked is also the most aggressive of the six and attacks any of the others I pair him with. (I'm assuming it's a rooster because it crows almost incessantly.) The trio and the other pair are all settled in and calm, with nobody bullying anyone else, and the aggro one is off in a cage by himself. Right now, each group are in large modified clear totes that are roughly 3'x2'x2'. A larger aviary is in the process of being built. The current bedding has been treated with Sevin dust in case the feather loss is mite/louse related instead of pecking, although since it's back of head/neck feather loss, I'm fairly sure it's pecking. I've never had to separate an aggressive bird before, so my question is: Am I going to damage him if he's left alone? Secondary question is, if the answer is yes, what the heck do I do with him to give him companionship without letting him pick on another bird? He's not pacing, but he's crowing a lot. Since he was in with the rest until just today, I'm worried I'm going to make him completely neurotic. As mentioned, he's the one most badly featherpecked. His head, neck, and top of his back are pretty much bald right now. Could the aggressiveness be a defensive issue that might tone down once the feathers grow back? Any advice is appreciated! Thank you!
