Hi I have a 3yr+ female rouen duck. Yesterday she was in obvious distress. She was laying flat out on her stomach with her neck stretched out on the ground. Occasionally she would get up to walk and her neck would almost hang down to the ground, like she could not hold her head up. I placed her in the coop last night and today she was laying stretched out again in her run. Her breathing does appear labored. Her mate doesn't stray and is being very protective. There have not been any animal issues as far as predators or something getting to her. She has always had a bit of a difficulty walking. It seems one of her legs is slightly turned in and she does fall occasionally. Could she have fallen and strained her neck? Anyone seen anything like this? thanks!
