Recently we had to get the flock in because of bird flu and they're inside, i noticed my only silky is looking very poorly and isn't eating a lot. At first I thought it was bird flu because we're looking out for that the most but she doesn't have a swollen head. Yesterday I went to pick her up and she didn't react, usually she panics, and I noticed she was pecking around for food but isn't eating the chicken feed or snacks (right now we have a lot of kale and cabbage left over from summer's crop) so I gave her a drink and she swallowed but wasn't interested. Her crop is a bit beaten up and is getting crusty, and my other girls are molting so It could be that, except they're not acting in that way, just loosing feathers. Does anyone know what this could be and how I can help her?
