Hey guys. I have an issue. I have two guinea fowl chicks at the moment who've been incubated by a chicken. They hatched fine, and the first two days have been great. But just now I looked at them, and both have a yellow discharge around the eyes. They seem relatively okay otherwise, eating and drinking normally and making noise as normal. But their eyes are definitely not normal, and I'm quite worried about them. Does anyone here have advice on what could be wrong with them?
