Hello!! I may just be overreacting, but I went out to check on my hens and one of my young black stars had her eye closed and it looked somewhat swollen. There is no goop or crust or any type of secretion- her breathing is normal. Could she have just gotten pecked in the eye by another hen? Can I do anything for her to alleviate swelling? Most other posts I'm seeing the chicken has some type of crust or goo on their affected eye and that is not the case with her. Any help is greatly appreciated!
