Corid is a brand I think. I can't find it here. I have Amprolium coming & am using the vet stuff meanwhile. I don't think she's ingested bedding . Her poos have become more watery ~ not surprising as she's not eating ~ & her crop seems ok. The other chicks seem to be gathering round her to keep her warm & I have been cuddling her on & off to make sure she's warm enough. She's supposed to be off heat as I said I wouldn't take anything needing heat as I'm not set up for it. I can get her to a vet tomorrow if she lasts that long.Corid is a good idea if she’s puffed up. Make sure she’s warm. Could she have ingested bedding? Is her crop emptying?
