I have a chick that is barely a week old and this morning I noticed one of its eyes was bulging. There is no drainage, no other symptoms, seems to be eating and drinking just like the others. Could this be from being pecked in the eye? I saw a couple of chicks pecking each other in the eyeball. The eye itself is clear black just like the good one... Should I be concerned? Should I isolate it? I hate to do that because he is used to being with 10other chicks... Thanks in advance!
