I have a two year old Wellie Roo that has started to walk like he belongs in the Gestapo. He has been doing that for about a month. I also noticed he stopped roosting on the perch, he started sleeping in a laying box. Now he aslo seems unbalanced. Sometimes he almost falls over. He is sitting down eating sometimes too, sometimes not. What ever is wrong with him is getting worse. He doesn't appear to be in any pain or distress. Otherwise he always been a healthy bird up till now. Any ideas?
