I have had these rouen ducks ( even though this pic was when i had chickens) since they were babies, but now its winter time and i live in Utah so i want to make sure there warm enough. They have this dog house that is insulated with hay in it for now i will get some straw, there is a cover over the entire kennel and since this picture i have put boards around the edge of the kennel to give them a wind break and to keep the snow out.The house is kinda small so im worried not all 5 ducks can fit in it, ( even though if there cold im sure they will squeeze) my ducks love to roam the yard so i let them out a few hours everyday to. Ive never had ducks in the winter, but they seem to love the snow. They find dry patches after a while and warm there feet up but other than that i just want to make sure there going to be warm enough with the coop i have for them. It can get 0 or even - here. Also do ducks need a light in the winter to lay? My girls have recently quit laying, i dont know if its the light thing or because i just got them a drake boyfriend?
