I have no lights and my hens lay I swear all year. They seem to lay better when it is crappy outside. HAHAHAHA. I have production reds. Just for laying. I use to feed them 16% laying pellets. Switched at the beginning of winter to 20% Purina Flock Raiser and oyster shells on the side. Plus I give mine scratch feed about every other day during the winter. Like I said, mine don't lay any different depending on the season. You do have to take into consideration I do live in SC. Cold this morning for here. 29. But will be 57 by the end of the day. There is a hen in the box at the crack of dawn already. They never stop.
