We've had a bantum Mille Fleur D'uccle for about a year and 4 months now. He hung out and ran around with his hatch mates fine for the first few months but gradually became a loner. We noticed that he would walk in circles where he was, not really "Go" anywhere. And he drops his head and goes to sleep all the time, like, right where he's standing. We laughingly call him our Narcaleptic Roo. By six months old, he seemed to become the outcast, never leaving the coop - gee if we saw him outside it caused us to call other family members to come see, "Ducky is outside! Wow!" When we'd put him out of the coop, say to clean or change bedding, he was right back in there underfoot. He routinely slept on the floor, if we put him on the roost, he'd fall off. Seemed to have balance issues and just all around be a doofus. If one of the other birds picks on him, he goes limp and plays dead, doesn't run away. And he's always the first one hit by lice or mites! Just this week we had a chicken friend over and she commented that he had a little bit of gunk in one eye. I wiped it out and she said it looked like he was blind - sure enough, he's blind in both eyes! Not sure how it happend, but can narrow it down to somewhere between 3-6 months old. Boy do I feel like a dumb chicken momma!
