My 3 yr old white rocks (none of the other birds) are getting naked necks. they all roost on the roost built to be a roost, 2x4 with 4" side up, right next to each other. Production has really died off, from 12 a day to 6 from 16 birds, and I'm seeing some feathers around the coop. Could this be moulting? History: I got chickens last June and these older birds joined in September. No problems until about a month ago their necks began to go bald. I'm hoping it is a bad molt since I haven't ever really seen one from my birds yet.
