My chickens are still laying. Not as many as they did in the summer/warmer months.
Every spring I start seedlings using grow lights and heating mats and covers. Every year I try to save seeds from the largest plants from the previous years.
Not sure how it happened, but one winter one of the boys got in with one of the girls and a month later she kindled and had 8kits/baby bunnies. Had to bring her and the kits inside the house. Of all the livestock I have, I think rabbit pee smells the worst. Not fun, but breeding rabbits in the winter is doable.
