We recently got new chickens and my silchins have been sneezing/coughing and closing their eyes. Just now one coughed(I think)...could be a sneeze... and a giant loogie flew onto the coop. It was clear and reminders me of mucus for a cold in a human. We have some serious pollen going on right now, is it possibly from that or should I consider treating for a cold? Otherwise they seem fine. Their faces are red(not much wattle to them... See profile pic) and I have seen them eating and drinking this morning. Edit:we just got these chickens Saturday and I'm totally new to them our first 4ladies.
