Kree

Good evening, I know there have been different discussions about this but I just wanted to check my own situation. I got 3 chickens last week and within a couple of days one had a bad eye, bubbling and looking sore. I read about different chicken eye conditions on different threads. The vet gave me kesium tablets and a pain killer but it doesn't seem to be doing a great deal. Another chicken now appears To have the same issue. I have pictures but not sure how to put them on here.
