I let my girls out a little while ago for their usual free range and treat time but my RIR hen doesn't seem to be seeing right. She's moving really slow and seems to have some depth perseption problems. If I hold something up for her to eat she doesn't seem to have any problem taking it from my hand but when she tries to peck at something at the ground (like grass) she keeps missing it. Any one have any ideas what could be wrong? I was already have a really bad day today and I was hoping my girls would be able to cheer me up, now I'm even more upset.
