My little Dutch Bantam roo Er's area between his eyes and earlobes are swollen on both sides of his head and he does have a little discharge (snot?) coming from his nostrils. The swollen areas don't seem to hurt; he let me gently touch them. He seems to be fine other wise -- eating normal, colorwise looks fine, still very active. None of the other chickens have this problem. He's only 8 months old if this helps. Should I worry about him or does he have something more then a "cold"?
