We just moved in last month and were in a hurry to get in before the first snows. We did, just barely. I know my birds do not have enough room in the tractor, but I belive that's whats keeping them happy and warm. I keep wondering though, soon it will be so cold here (-30-35) that they won't venture out to get their food. I take them hot water twice a day to drink as long as it isn't frozen. The only option is to move them into the second room of the wooden shed. The rabbits occupy the first room and I have always been told to never house birds and rabbits together, but I am so worried about the birds in their little house. I saw an earlier post from a gal in Alaska about a ceramic heater, a few nestboxes and an insulated shed. I can hang a light in there, put wood down on the rotted floor and fill it with straw. There is plenty of ventillation and they would have a more cozy place to winter over. Well, roomy anyway, and they wouldn't have the windy run. And hopefully I'll get a few more eggs. I have such plans for that shed in the spring, and they will have a huge run. I just wish we had found this farm to rent earlier, my birds would have a better house.
