Hey Chicken experts! We are going into our first winter with chickens in North dakota, and I'm looking for some suggestions on feeding my flock in the winter. We let them free range when were playing outside in the summer, but we wont be out as much as it gets colder. Right now they get the Omeaga 3 feed, kitchen scraps, and scratch grains as treats from the kids. I gave them a little canned cat food when our older birds were molting. Should I continue this in the winter for extra energy? If so, how often? Should I give them suet? They have a great coop that has a light and timer, as well as a heated waterer, but they don't go in the coop besides to lay, or sleep. Is this normal? It gets really cold here, just want to keep the girls safe! Thanks!
