I have shut mine in, but did let the kids out a wee while. The snow and frosty weather makes them go mad. Running about like mad things. I went out yesterday morning it was around - 7 , and in the shed had a couple of milkers and goatlings airborne! jumping about all over the place. butting each other. I let the kids out for a while, made it easier for me filling racks etc. they were running about like mad sniffing and trying to eat the snow.
