This will be our first winter as chicken owners. We have three adult buff orp hens. We converted an old outhouse into a coop for them when they were old enough to live outside. Here it is: It has narrow rectangular vents covered with hardware cloth on the top and bottom side walls. You can see the vents above and below the nesting box. Here you can see the extra vent my hubby added to the bottom of each door. They are also covered in hardware cloth. The vents at the top are covered in some sort of thin hard plastic. This is the right half of the coop. One of my girls was busy laying so I didn't take any photos as to not disturb her, but the left side matches the right side. The only difference is the left side has the nesting box. We removed the partition wall and toilet seats. We put a thick board on top of the toilet boxes, then put a perch on top of that. These next photos are various places the chickens free range during the day. We live on the 49th parallel, where Father Winter comes early and brings plenty of snow with him. My questions are: Should we build a covered run for them? Is it safe for chickens to run around on the snow or will it hurt their feet? I want to allow them to free range over winter, but my hubby thinks they should be kept in a run. I don't have a problem getting out there with a snow shovel to ensure they have a patch of ground they can peck at, but if it's better for them to stay in a run over winter, do you think the coop they have now is adequate to attach a run? Responses greatly appreciated!
