I am desperate!!! My 3 buffs and 1 black austro have not layed any eggs in 4 months. Plenty of water, Layena crumbles, kitchen treats and oyster shell. They free range a few times a week, have a light on a timer from3 to 11am. What am i missing? One of the buffs looks awful with missing feathers but has looked that way for months and not completed the molt. I am afraid if they don't pick up the pace they'll have to go. I mean...I need at least a few eggs!!! HELP!!!
