One of my muscovy's started limping really bad last week. I checked the leg for breaks and couldnt feel anything so I passed it off a sprain. I put her in her own pen so she wouldnt get trampled. Today she started limping with both legs. Its to the point where she can barely walk at all. She flaps her wings to get around but other than that its more of a crawl. When I watch her try to walk, as soon as she goes to put weight on the leg, the joint bends and she falls down. I thought I read something about this somewhere but I cant remember where. I was wondering if anyone has any experience with this or knows whats going on?
