Poor Corey! Unfortunately, I have no knowledge or advice to offer. Timber has a toe that is deformed (for lack of a better word), but it hasn't affected his ability to perch or get around. A few years ago, he developed a seizure disorder. As a result, the vet recommended that I move him into a smaller cage, switch to flat perches, and keep a towel on the bottom of the cage for cushioning at night. This was all in case he had a seizure since falls can be damaging when they are helpless. I don't know if the flat perches might help Corey or not, They are basically just pieces of wood that are broad and flat. However, I will say that after a time, I noticed Timber sleeping on the towel more and more during the nights. He won't while the lights are on and people are around, but I've caught him sleeping there several time when I've surprise him before daylight. God bless in your quest to keep Corey after and content.
