i have a 1yr old gray who scratches and plucks, and has done since i've had her (11 weeks old). her diet is good consisting of harrisons biscuit (high protein for 6 months). she cant be bored as i interact with her often, she hasnt been moved for a long while, i moved her more in the midlle of the room so there is no draft, and she gets 12 hrs sleep at night. i've tried AVIbird smoother topical spray for 10 days when she had a really bad pluck. she was ok 1 night then the nxt morning she had really attacked her back. i also tried some pluck no more type spray but since she doesnt use her tongue to pluck found the stuff pointless cos she wont taste it. shes started on her chest and under her wings (amrpit area) of late and its getting more worrying. it looks as though they itch because of how she reacts. i can see black spots but am unsure if its the feathers she pulled or mites? shes ok when i spray her with water for a time. help help help.
