Both our emus started loosing a little bit of feathers on their sides. We thought they were rubbing up against something that was pulling them out but they have now lost a LOT of feathers. And I do mean a lot. I look and I don't see any bugs on them, but maybe I'm not looking for the right thing? Any ideas? Do they molt? I am trying to find a vet that does house calls which is turning out to be a fun adventure... Thanks SO much!
