My year old Buff Orphington roo was having some balance issues last month and now the problem is wayyy worse. He can't really stand but he crouches down instead. Whenever he walks he doesn't stand up straight but crouches and waddles almost duck-like. He takes slow uneven steps and trips often. At night all the other birds perch in the rafters of the coop but he remains grounded. Whenever I sit him down after holding him, he tips over forward. I have no idea what is causing this but maybe he had a fight with the other roo. They don't usually fight but who know, its a possibility.
