Sally, I really feel for you but the only ones that I ever heard of laying that many double yoke eggs are the Red or Black stars. But even they quit after they get into rhythm. This usually happens with young girls just starting to lay but once the egg tracks get to working it will quit. You may get one once in a while but I've never had this with the reds.Is there anything you recommend I do? other than ordering more chicks? I really like these hens. Having only the 3 heritage hens I have become quite attached to them and the idea of having their offspring for years to come. My laver chickens get attention too but not nearly as much of me watching them forage.
Sorry, can't help much. I will do some research on this matter and see if I can find anything to help you out. I really don't think that your feed etc has anything to do with it but who am I to say.l lol
