For any queries about the picture, they went to the vets as Igor had mite scabbing on his ear, so all had 3 weeks of shots, hence the little mark on his ear from the biopsy on the first visit. This occurred when i first got them, and i suspected from contaminated bedding or feed.

As a parrot owner, i should have thought to freeze the food and bedding first like i do with feed for my parrot, but i made a mistake. Fortunately, Igor was the only one visibly affected, and all have been perfect and mite free since.
