One of my hens started off with a watery eye which within a few hours it comoletely closed, I then separated her and brought her inside, the next day it was both eyes, she has stopped eating and drinking so I had to squirt some antibiotic treated water in her mouth. Next day she had a white film over both, I cleaned her eyes out and started giving the rest of my flock antibiotic treated water. She developed a cough and today she doesn't look good. When I went out this morning I noticed that another hen that was in the sick ones coop had a watery eye as well so I just separated her from the rooster they were with. And advice? Should I just cull both now so there isn't anymore spread?
