So I went out to put my ducks in their coop tonight and my female Runner/Pekin was laying down with her wings spread on the ground. When I got close she started flopping around and it was obvious she couldn't stand or walk. I thought she may have been attacked by an animal but there's no blood on her anywhere and her legs don't appear to be broken. I checked her webbs too and I didn't see anything out of the ordinary. I'm going to take her to the vet as soon as possible but I was curious if anyone else has seen anything like it.
