Ours usually lay all winter without supplemental lighting but they stopped not long ago. Rebar Ranch ran out of Flock Raiser so we fed a layer pellet until they got more. I wonder if that had a negative effect on their laying. I have been blaming the cold and the stress of our new LGD going into their coop so I had not considered the feed change to be a possible factor. We have also stressed the flock by selling some hens as a flock reduction prior to hatching, which I will start once they are laying again.
I have taken such a long break from hatching due to my injury and surgery that I am looking forward to starting up again as it warms up (when the eggs get too cold I don't even try hatching them). I have a Silkie sitting on eggs but nothing in the incubators. We still have plenty of eggs to eat in the fridge so I am going to make quiche and boil some for egg sandwiches to clear them out.
