Last night when I went out to put my ducks away for the night, one of my Cayugas was sitting next to the shed. normally I have to chase them in (I think they enjoy it), but I had to nudge her yo get her to go in. This morning she was pretty much the same, not wanting to come out. By this afternoon dhe she was walking ariund a bit but mostly just standing. She went back inside gor awhile and I went out to check on her. she let me pet her which is unusual, they normally don't like to be handled. She was very calm. I picked her up and brought her outside to her water and she drank readily and she is alert and preening herself, just not moving around. I had to carty hrr bavk to the shed for the night because she didn't want to walk over there. She is not lying down, just standing there and her gait seems mostly normal. Maybe a little stiff snd slow but no other issues. I am not sure what to do for her. Any ideas are appreciated.
