I am trying to figure out what is stressing Chatter, my male eclectus. His previous owner had him on a corn mash and said if he didn't get the mash, he plucked. We have had him two years now. He is on fresh chop, which has some corn in it, nuts, et cetera. He likes all people, but I am his chosen. Unfortunately, he does pluck so not sure of stressor. I discourage him feeding me. I discourage him masturbating on me. So not sure if this is why he is plucking and i should let him? He is only caged when we leave the house, which is seldom. He is in the living room with us. Any ideas?
