Hello, I recently had four Muscovy ducks hatch about 2 months ago and keep them currently in my garage in a metal horse water troff. They always have food (Chick starter/grower) and water to drink as well as a heat lamp. I will let them out to let them stretch their wings and legs and run around and go swimming in the little kiddy pool I have for my other adult ducks. Yesterday I let them in the pool for a little ran in the house to switch out laundry and when I came back out I noticed they all were out of the pool and that when one of them walked it would hobble. I never noticed this before and am not sure if this was from getting out of the pool or if there was something else wrong. The leg does not seem to be broken, I picked him up and felt his entire leg and he did not seem to show any type of pain or anything breaking or dislocated. I had him flex his toes around my finger and he did that just fine as well. I am not sure why he limps and will extend his leg out to walk rather it be more or less under his body. Could this be a result from not having a large enough area to run around in everyday? Should I move them to a larger pen that is in the chicken coop and just transfer the heat lamp, food, and water?? Any thoughts?? Thanks!
