If it was running around a lot or something, it might of pulled a muscle. I pulled one in my leg yesterday and i can't run at all. my ducks pull theirs sometimes too. Or maybe someone stepped one it's foot?
A pulled muscle is the same as a sprain. Rest and the liquid B complex should help if that is what it is. My Runners do it quite a bit and I let them rest using a dog x pen so they can be with the flock but aren't moving around a lot. How is your duck doing?
well, jake is his name, but he does good after spending a few days with star, his mate in his kennel. i let him out, and he limps quite soon after walking. maybe right away. now, i cant really see him walk around in his kennel, cuz they just lay down and sleep. i gave him more complex today. i didn't see him lay down a lot today when i let them outside of their kennel to free range. i think he might be getting a little better
