We keep five backyard hens in a 10 by 10 dog kennel (roofed) at night. They sleep on perches. There is a doghouse inside filled with pinestraw and they lay eggs in there. During the day they roam the backyard. This has been the first fall/winter, though. that we've done it this way and I am worried about the hens being in the wind. They won't go into the dog house - they want to roost, of course. Last winter I had only 2 birds and would house them in a closed, straw-filled plastic dog house in the garage (entrance blocked with a screen) at night and let them outside in the a.m. I think we will hit freezing tonight here in N.C. I can go outside right now and scoop them all up and put them in the garage, though with 5 they will have to be split up. Thoughts on the open-mesh of the dog pen and nighttime?
