In my area (east/central Kansas), the snow has been a problem, but the frigid temps are worse. the overnight last night was either -3 or -1 depending on your source. Even with the heat lamp by the roost, the coop gets down into the single digits. One of the girls wouldn't come off the warmest spot on the roost this morning to get treats. Poor babies.
I shoveled their run (well part of it) 2 days ago, didn't do any good, there was still that evil white stuff on the ground, so I spread out part of their straw bale yesterday, and they came out and scratched around for a while. I think the high yesterday was 14 or so, but they didn't mind that since the wind was shielded. Today it is 9 and they are out scratching in the straw. Tough little birds. I'm getting 3 or 4 eggs a day from my 7 girls (and they have only been laying for a few weeks).
The older I get, the less tolerant I am of extremes of any kind -- weather, religions, politics -- you name it, I want nothing to do with the extremes. Right now I'm focusing on cold !! Brrr.
