have eye problems but the hens (2) eyes are fine. The roosters are eating just fine the yellow on their beaks
is from eye yolk that I feed them with their feed which is scratch grains poultry feed, cracked corn and All Flock 20% protein pelleted poultry feed or Layer poultry feed. They stay in the coop all the time I purchased them this spring at a swap meet. I have a mixture of other chickens that are just fine. The rooster do not crow but do scratch at their food. Some days their eyes are partially open.
It looks like they probably have a respiratory disease. I would treat their eyes with Terramycin eye ointment or the original Neosporin without the pain reliever in it.
