Hi everyone! I have a little chick approx 5 weeks old, that doesn’t eat much and I only recently noticed some crustiness on the corners of its mouth, so I looked inside and found this yellow stuff. I have never seen this before. After some google searches I have realised it’s either canker or thrush. I’ve ordered some Ronivet-s online because at first I thought it was canker, so that’s on its way, but should I be treating it for thrush? Thank you in advance.
