Hi, I have four chickens 10 months old. Buff Orpington, Olive Egger, americauna, cream legbar. It's winter here and we are not forcing lighting. My buff is still laying eggs, but the other two blues and green layers have stopped laying. Are others with blue and greens finding this normal? Do the blues and green layers just stop all together or do they lay just one a week? Thanks! They seem healthy. Normal poos.
