I am wondering if poultry people with more experience that I have can give me some feedback for my winter plans for my girls. I currently have 6 hens, 3 production reds and 3 black sex links. They are about 7 months old. I am new to this whole venture. We live in Western Maine and temps in the winter can often go below 0 (-20 to -30 is not uncommon in the winter). I have the girls in a small chicken house with a moveable chicken run that we move every couple of days (too many coyotes and foxes to let them run free). I just had a 6X10 shed built for them. It is not insulated but I am thinking that I will just move the smaller chicken house into the shed for the winter. Since they are used to roosting in the smaller house anyway at night and laying in the nesting boxes in the house, I think they could just continue to roost in the smaller house at night and stay warm at night that way. They just sleep in a big pig-pile together anyway. Does this make sense to anyone else? I want to put a light in there to keep egg production up, and I have a heated water bowl for them. Does this sound like a good idea??
