One buff on barred rock both about a year and a half possibly two. Haven't got a egg since I got them. They've been wormed too. I'm at loss on what is going on. I know they are older but I would at least expect at least a egg now and then. They aren't sick, healthy weight and all. They aren't stressed they free range in a area about 800 Sq feet with a 12×10 run and a large hen house with nesting boxes
