Yellow Headed Amazon Parrot / Leg Problem
We have a Yellow Headed Amazon Parrot, 30-35 yrs. old. Recently he seems to have a stiff leg. Doesn't want to bend it. Hold his,right, leg up in the air, and sometimes falls off his perch. He slips off the perch at night, sometimes. This has been happening for about 1 week. He's eating normal, everything else is normal, nice shiney coat, signs, seems happy as usual. Just holds his leg up.
