I recently introduced 4 new buff orpington hens last week. When I took them home I noticed one (about 3 or 4 months old) was sneezing. Didnt think much of it then but now a week later and my poor Buff Orpington Roo is sneezing , yellow snot coming out of his nose, eyes are watery, acting really sleepy during the day. He is about 7 months old. They all have been eating, grass from the yard, chicken scratch with mixed grain, and drinking fresh water. I keep them confined in my garden and always keep their coop pretty clean. His feces is looking normal from what I can tell. Please look at the pics of him below and any advice anyone has would be awesome! Thanks!
