My 2 month old Rouen is acting very lethargic. Her sibling of the same age is doing perfectly fine as is her other hutch mate. She’s quite a bit smaller than her sibling. We just moved her outside full time about a week ago. Wile letting her and all of the other ducks (11 total) run around and swim we noticed she was just sitting there. I went to pick her up and she didn’t run away like she normally does. I checked her feet, wings, feathers and crop and I noticed her crop feels totally empty. I tried feeding her and she wouldnt. I got her to take one drink of water I don’t think she got into a fight with a hutch mate because she’s in our “sweet baby” hutch with her sibling and a young female runner, we also have a “mean baby” and an adult hutch.
