It's down to 19 here now, cold cold, and time to wrap my pen up in 6 mm clear plastic. I spent good hard earned money to get my pen redone this spring and I know it will be money well spent. I had a huge kennel last year, had the cross bars on top and them tarped the top and all the way around, but what a pain that turned out to be. The top got laid down with snow, we kept jumping up and knocking it down, it melted and made water, the tarps on all sides of the kennel blew in the wind and no matter what we did they flapped and blue in the wind. We were forever zip tying them down lol. This year I had a pen built, with a slanted roof, heavy hard wire, and bigger . Today we wrapped half the pen up in the plastic, making sure it was stapled down well, and tolorrow the other half, then I'm going to go inside and do the same. I want my girls out of the wind and I do not want to have to be doing this in sub zero weather ! Getting out the tin can heater and I'm so glad I got an electric door opener this spring. No more getting up at 7:00 ( it's still dark here at 7:00 am lol ) to go out in the freezing cold to let the girls out and unfreeze the water. Best use of my tax money I ever spent! Increased the coop, rebuilt and had the pen made bigger, added electricity, and an electric door opener. It was expensive, but well worth it!
