About 2 months ago I traded a couple of roosters for two Buff Orpington hens. They were 2 years old and 1 year old. They were massively huge and overweight, I could tell when I picked them up. The fellow that I got the hens from said that they were not laying anymore. And they haven't yet. During the past two months these birds have lost an incredible amount of weight, and I think that they are of a proper weight now. They have been exercising their brains out, fed a good quality layer/breeder feed. I have an enormous area that they forage in, along with their other pen pals, hills, trees to go around, grass and bugs to eat, everything imaginable. They have done nothing but walk now for two months, over some ruggedish terrain, they are slim. They clearly have not been laying for months. They have 15 hours of light, through light I give them with a timed light system. I have heard that fat deposits along the oviduct and if birds are overweight the have issues with egg laying. Is this true? These birds are not old by an stretch of the imagination, mother and daughter. Will they ever lay eggs again or does the overweight, fat issue make for a bird that never lays again? I have no clue about this and would really be interested to know. They really are lovely, huge and just drop dead gorgeous. If you know this answer, please elaborate deeply so I fully understand the principle of overweight hens. What age should a Buff Orpington hen lay until?
