I have just started keeping chickens and am enjoying it so far. I have 10 pearl white leghorns and 5 red stars that are laying, and I have 5 arucana chicks that should start laying in July or August. I live in western Colorado and love living in the mountains. I am worried about "winterizing" the chickens and making sure the hen house is warm enough yet not so air tight that they get sick from that. We made the hen house out of mostly recycled materials, reused wood and such. SO it is not the prettiest thing around, but it is functional. It is 4' x 8' x 5' high with 8 nesting boxes and 2 8' long roost bars. The attached run is 8' x 16' and is fully enclosed. I always welcome learning new things and find it helpful for people to kindly let me know what works for them and what doesn't. My parents had chickens when I was a teenager for several years, but at the time I tried hard not to like it. Thanks for sharing!!!
