We also put up a hard clear plastic corrugated sheet over the Hooligan's coop windows to help create a wind break. It's clear so it allows the sun to still shine through and heat up the inside of the coop, and keep them on normal daylight hours. It cost around $12 (that was last years price, it's at $14 now).
Since most of them sleep outside on the roof, we'll see if they figure out it's warmer in the coop than on the coop. It's either that, or find a really close friend to snuggle up with overnight. We'll be out to check on them Wed., after the deep freeze. I'm interested to see how their combs and waddles fair.
Buckeyes have been bred so their combs and waddles are small and compact, so the influence of freeze is limited.
My Red Stars have rather large combs and waddles (similar to the Rhode Island Reds), so their exposure will be greater.
I'm sure they'll be just fine, but Mom's do something really well; we worry! So until I can see them, do a head count and make sure they are all accounted for and seem healthy, I'll continue to worry.
The cold weather makes you stop and really think about how prepared you are. Do you have the proper items to cover your plants, and care for your animals? We can get very lazy in Florida or other warm southern states, having wonderful weather, but we need to be prepared for all eventualities.
I'm off to make some hot chocolate, put on some warmer socks, and get my day started! Have a good day...
