A friend who sells eggs just asked me for some because she can't keep up with customer demand. She ordered 3 Rhode Island Reds and 7 Barred Rock chicks more than 6 mos. ago and out the ten hens she gets only 4 very small eggs a day. ( Her other hens are older and not laying at all--no culling here.) What would cause these hens to not be laying regularly. I've attached a picture of her coop and run set up too. She has the hens going out of the coop to outside laying boxes. I don't think that's the problem as she has raised many chickens in the coop and they've all caught onto it! The nest boxes are accessible from the side. The run is a very large fenced in area under the trees.
