I have 5 hens who are not yet a year old. Their laying has tapered off a bit but I am still averaging 3 eggs a day and the weather is between 20 and 34 degrees and very humid because of snow and rain. I think they are still laying well because of fermented feed, greens and other raw fruits and veggies I chop. My neighbor has had kale, spinach, cabbage, and broccoli that he shares with me. Had plenty til this snow. So we'll see. I may start sprouting for them. I also have a clear panel roof so they get maximum sun.
