I'm at a loss as to what could possibly be keeping my girls from laying. Yes, they went through a molt and it seems that they have constantly been growing new feathers over nearly 8 months. They are alert, healthy looking, good weights. There are no signs of parasites. They have well ventilated coops, a huge run and have been free ranging. First I thought they had to be laying somewhere else but after many thorough searches of the yard there are no eggs. I've also not heard any egg song. I've tried switching food, I've tried hot sauce, I've tried DE in their food (just in case) but nothing is producing eggs. One girl lays one egg a week and we have six girls. Our weather gets to the thirties at night but this has gone on since summer. The breeds are Barred Rock, Orpington, Delaware, Black Star, RR, Australorp which are all supposed to be good layers. They are maybe 1 year plus. Not very old. HELP!
