Thanks for all the replies, everyone!
For those that live in Mane, I live in New Portland, near Sugar Loaf.
I wasn't expecting them until Thursday but I got the call from the farmer's union on my way out of the office yesterday afternoon.
Picked up the 10 babies and got them safely home. We live on a VERY bumpy road and I was afraid they'd get some version of shaken baby syndrome but they seem alright.
The floor by the wood stove was indeed too cold--they were all hunched up--so we moved them to an elevated spot. I've got it all cordoned off with blankets so the warm air won't just go upstairs behind them. The heat activated fan on the stove is blowing warm air straight at them. A towel over most of the top to keep in the heat, and a blanket around the back edge of the box. Also, a gallon jar of hot water in the middle of the box.
I think they're doing alright so far. They did mostly sleep together between the blanket and the hot water jug, but when I checked them at 6 Am, they all got right up and started milling around eating and drinking. It's funny how they're like people in that some of them seem to want to be near the warm thing as much as possible and others are just fine. The golden comets seem to need less heat than the black links...I wonder if they're a day older.
Anyway, thanks for the help (as well as all the future help I'm sure to need). They are very cool. My mastiff thnks so too, so we are working on that.
