I have a 1 year old pekin drake, who started limping one day. we checked for bumblefoot, but that wasn't it. Now 3 weeks later, his leg and foot are very swollen. his leg is warm, not super hot, and he's still eating. I would love to get him x-rayed and treated, but that costs at LEAST 280$. I can't lose him! please help before it's too late!
