One of my year old roos was gimpy yesterday, and very lame this morning. I unfortunately had to chase him a bit to catch him (probably making it worse), but I thoroughly checked his right leg and foot and do not see anything obvious. When he sits, instead of folding both legs underneath him, he keeps the right leg up on his foot, sort of tippy toed, with his right hock up. So, I'm thinking it's in his shoulder. I did palpate his shoulder when I caught him, and again, nothing unusual. We have a very large barn, and I hope he stays in today. My flock of 6 hens and 2 roos usually free range during the day. We have been very careful lately though, due to mama foxes lurking about (who grabbed ahen last week). We have a large coop, and I probably could put him in it with his favorite hen, however I feel like that would stress them both out and end up with the whole flock calling for each other. On the other hand, I don't want him to struggle and try to keep up outside today either. Or get picked off by a predator. (Esp. since the two roos were alarming very loudly yesterday...) Any opinions? I also want to get an aspirin in him today, for some pain control. His is a large Speckled Sussex roo, probably 8-9 pounds, si I'm thinking half an aspirin? Thanks for any input.
