Hi all. I have 8 RIR pullets. About 8 months old. They seem to have some type of respiratory issue going on. Wheezing and coughing. One has a runny eye that seems to be closed frequently. They are eating and drinking like normal. It has started to get chilly where we are. The nights drop down to the 40’s. Not sure if this is relevant, but wanted to add that detail. Just curious about remedies/medicines anyone can recommend. Is there other symptoms I should be looking out for in case it’s a more serious issue? TIA.
