Darl, my BO cockerel, seems to have poor eye-beak coordination. When I have a treat, like a half of a grape, in my fingers, he bends his head way down to take it from the bottom. The pullets don't do that. Yesterday, I switched to a horizontal nipple waterer. He understands that's where the water is, but can't seem to understand the concept of pecking the silver peg to get the water to come out. Instead, he tries to bite the whole nipple. The girls figured it out right away. Yes, he is getting water; I saw him get some, but he also pecks the side of the nipple too. If I put the guts of a melon on the ground in the run, he seems to have a hard time picking up the seeds. He pecks next to a seed several times before he gets one. His eyes look fine, he doesn't run into anything. Maybe he's far sighted and can't see clearly up close? He's way too young to need bifocals.
