EYE GUNK & BUBBLES
Have 13 adolescent chickens mixed in with 12 adult chickens, one adolescent is smaller than the rest. Went out this morning and the eyes on the smaller one are gunky with one completely closed and some bubbles. Holds other eye open but full of gunk. Other chickens pecking on this ones head pretty consistently. This flock was laid and hatched with us so there has been no introduction of new chickens. She is eating fine. We Have taken her out of main population so she isn't being picked on and put here with five younger chicks in a separate area. Suggestions as to what could be going on?
