My OEGB is 3 months and seems to be scratching his head and digging into his wing a lot more often then my other chickens. I was planning to put him in with the rest of the chicks that i already had but hesitated once i relized it. Could he have lice or some other type of bug that could be making him do all this scratching. Also if he does seem to have something, how can i get rid of it??
