I was holding off on posting because of all the problems with disappearing posts, but figured I'd just go for it.
We're now up to three layers.
Besides Rufus, I haven't been able to figure out who the other two are. But, whoever has the darker brown eggs has started the trend of laying in the shavings in one corner of the coop instead of in the next boxes. Even on days when there have been eggs in the proper boxes, I am finding a tiny brown egg in the corner. Not sure what to do about that but am hoping that she will figure it out.
Babies also experienced their first snowfall. They were so curious about all the white stuff.
The first snow was just a couple of inches, but the next was 9" so they are frustrated that they can't move around as well. I do shovel out a little patch of grass for them so they get some relief from the run, but on days like today when it was -1*F when I let them out of the coop, they are pretty content to just play in the straw in the run and not go out at all. The run is large, so they have plenty of room, and scratching through straw seems endlessly entertaining for them. I just hate seeing them shiver in the cold.
Amazingly, they seem to be able to keep the coop almost 20*F warmer than outside temps when it's closed up overnight, with no extra heat source. All that body heat they give off! I do have it bedded deeply in shavings, lined with a layer of insulating wrap, and rake up a lot of straw around the outside- but still, this morning it was -1* and it was 21*F inside the coop before I opened the door- it quickly dropped to about 12*F when I was mucking it out.
