Your so funny so you think Tevye liked the assorted colors? lolWe did try cat kibble we still had from trying it last summer/fall when the flock started molting. Most of the ducks didn't like it much and I don't remember where she was on it. Tevye is the only one that ate the cat kibble like crazy - probably all the assorted colors. I think that she just generally doesn't have much of an appetite for anything, but favorite treats can override that feeling to a limited extent. Today is only her 4th day without antibiotics and although she had a day with yogurt and is getting probiotics in her water, I don't know how long it should take to get her appetite back. Especially when her crop is being filled twice / day. I will certainly ask the vet about it as well as observations about the dried on poop (haven't seen it in 2 days), tail wiggling, when she should stop getting silver polish on her butt, when she should be able to see the light of day (that could be depressing her if she is feeling well and might throw off her eating too) and when she should be able to go outside - once she is eating normally of course (I would put Kaine and Tevye in the jail for at least a couple weeks if I reintroduced her and all seemed well.)
All the others may have to have sun glasses when Casey goes back outside her butt will be so shiny from all that silver polish.
Poor thing is still in the dark too. That could very well be one reason her appetite is off. {Cave Duck}
Well all I can say is I am very impressed with all you and Yvonne have done and the great care she is getting.
