We are new to having chickens. We noticed yesterday that 2 of our chickens have runny eyes and noses. one of them just sits in her perch with her eyes closed with what looks like an inner lid covering her eyes... then a couple of the new ones have combs that look pale and bumpy... are they dying? What do we do? Do we quarantine the others? Do we have to kill off the sick ones and can this spread to our goats that hang out with them or our dogs and horses and us humans? Help!!!
