We have owned our African Grey for a few years now. He was bonded to me, extremely loving and gentle, stepped up on command, didn't bite or anything.
A few weeks ago he lost his balance on his cage and flew into the wall in the hallway. Doing this he broke one of his feathers, crapped on the floor and stepped in it. I snipped off the broken feather (hoping to avoid him from picking at it or causing discomfort) and then I took a paper towel to wipe off his foot before he stepped up.
Ever since then he has been biting me, refusing to step up unless it's bedtime. He has also gotten more close to our Quaker, where as before he would run away from him, as though he found him annoying. The quaker is needy and always trying to stand near the Grey. They have started preening eachother and acting like they want to feed each other (both are males.) Their cages are together and Hiei loves to get out and play on both cages and play inside the smaller cage for the quaker (we usually put the quaker on a play gym so they only get together when we're watching.)
Anyway, I don't know what to do. Hiei keeps biting me horribly and it seems like he is scared of me for some reason. He looks at me and looks scared and shakes slightly. I have not done anything to him, no yelling or hitting. Did I somehow traumatize him by wiping off his foot? I seem to remember doing it once before with no issues. I need some advice on how to get my friend back.
I am considering separating the bird cages but thinking that would be a bad idea also as they would just call to each other and drive me nuts with screaming.
