Thanks,guys...
Johnd: yep, the white one is a Delaware, and we have a Buff Orphington (the red one) and a Dominiquer (black and white). The are all 3 very sweet, but none have laid us any eggs yet...I know they slow down (or stop?) in winter, so I'm not sure if we will get any before Spring...just not sure how that works. We got them in July when the B.O. was 5 weeks and the other two were 1 week old or so...
We have the coldest night yet last night (in the teens). Hubby usually opens the coop door before sunrise on his way to work, but this morning he asked me to do it about an hour later because it was so cold and dark. I was just a bit worried about how the girls fared, but when I opened the pop door they all piled out, clucking and humming and ready to start their day. So, it seems if you just get the wind off of them, that is all they need. Whenever I start to feel like they need a heat lamp, I remember the "open-faced"coop I saw featured on here, that only had 3walls, and the pic was taken with 2 feet of snow on the ground...the poster said they chickens did great, and it was how they built coops in the old days.
I say this as I sit wrapped in an afghan on my couch sipping hot coffee, very, very glad it isn't the olden days anymore. Brrrr.
