About 3 days ago it was raining and I noticed 2 of my chickens where wet. The next day they looked like they might have had a cold in there eyes? They where foaming(eyes) and there face had hard crusty bumps on it. That day I brought them in gave them a bath but still like that.2 days later they are alot better as there eyes are fine but still has some bumps. Anyone know what is wrong?
