Just remember...smaller doesn't mean warmer because ventilation is most important, and ventilation means it's not going to 'hold heat'.Unfortunately no, not yet. My full attention was needed elsewhere.....as it turned out, my kitchen was in dire need of some "small" repairs. And, as everyone knows, as soon as you start fixing something, you find 10 more things that are wrong, so the fun I was having building the coop needed to take a break until spring.
Taking a break from the coop is a bit of a blessing in disguise though....we've has some SERIOUSLY cold weather in my area this winter (many nights 5 below zero with wind chills as low as 20 below) For my 2 girls, I think the big coop would have been too cold for them, but with their old/current coop, they stay nice and "warm" even during the super cold nights.
Bright side, I will be making a small addition to the new coop in the spring.......a small 4x4 addition to one side that will be a separate "coop" with floating walls so I can insulate it with hay and really keep them out of the cold if they need it for next winter. Then I can pick up my new chicks in the spring.
Larger is better because the ventilation can be up high and easier to reduce drafts directly on chooks.
