One of my muscoviy hens is acting strange, she will walk in circles then lay down, the other day when she was doing this she acted diorentied, and when i picked her up and waved my hand in front of her I really don't think she was seeing. she was like this for most of the morning, I put some nutri drench in some of her water hoping it would help. Then today i was sitting on the patio watching every one and here she goes again walking in circles then at break neck speed with her body low to the ground like she was chasing something she woukld take off. she didn't fly just moving really fast. when she ran up to her sisters they all started their muscovy thing making noise and walking together, she seemed to calm down some, she is eating and drinking, but I moved her to her own little spot in their house so the other girls wouldn't pick on her over night. other than that they all free range together, but am keeping her inside the large fenced in area till I know she is okay. Has anyone ever seen anything like this before? i have looked on line and in Storeys Guide to Raising Ducks and don't see anything. I am thinking maybe seizure? I just don't know.
