I am new to having chickens, we raised them from chicks and they are about 10 to 12 weeks old. The other day I noticed that one of my hens had a white spot on her eye... I thought maybe it was just some debris or some thing and that it would go away, but today I noticed it is still there, and upon a closer look I am concerned that it is possibly something that we should be worried about/need to take care of. Has anyone ever seen anything like this before? Any input is appreciated!
