My husband and I just recently rescued an Umbrella. She has settled in rather well, but out of the blue the last 2 days she has started biting, and biting very hard. She went all the way to the bone on my husbands wrist. She is some where around 5 or 6 we think. The people who had her kept her caged and in a dark room almost all the time. She can be doing great and then just lunges at my husband. We do know that the wifes husband that had her hated her and tormented her. She was getting to where she was screaming all the time, and because of the husband she had to go. She goes to the vet tomorrow for nails and exam. She has started plucking a bit, but not much...I guess my biggest about Lily, is what is the best thing I can do about the biting. I have been bit by big birds before but never like this. Any help or suggestions would be greatly appreciated...ty
