Having gone through several winters with the hens now, I have decided that they would be better off with more shelter over winter so I'm considering building a row of breeding houses with covered pens in front and deep litter in both house and pen. Plus a gravel path along the front, also under cover for human access. I was thinking of something like 8' x 8' for the run and for the birds to be in there from the end of October to the end of Feb depending on the weather. Then they go back out into the field pens which are 10m2 per bird. Does that sound enough for 6 hens and a cockerel? At the end of the day, most days they are just in the house or hunched up under shelters during these months anyway and you end up with a mud bath around the house which can't be good for them (or me). Would also be much easier with freezing drinkers and stuff like that.
