Bob, the cardboard is a good idea. We do a lot of work in a neighborhood close to here just across the border. Those people have dirt floors and most of the houses are probably not as nice as your chicken coop. They use cardboard for insulation, too. Last winter they had a child die in the neighborhood. Many of them have no electicity, so no heat lamp there. I got to have a small part in bringing an awful lot of blankets, gloves, and hats over this winter. All of this worry with my chickens has kind of convicted me. I need to be concerned about my friends over there instead of my chickens.
I hope everyone is having a fun night! I got to be home with my kids after getting a new vehicle. What a blessing! Now I don't have to listen to my kids whine about not having any room. I haven't been this excited about a vehicle since 1996.
Mahonri and others, how is the hatch coming along? I will have to look for that thread. How exciting!
