The barn pens are dry. We use a heated water system for hydration and they get fed standard rations. That's it. Nothing particularly odd or unusual. The temperatures folks are experiencing the last few days are simply called normal up here. Happens every single year. Winter starts rolling in around Thanksgiving and we hope the snow is finally melted, in the shade, by the end of April. Shrug.
The birds do just fine. It's not like winter sneaks up on them. It's gradual. The Nelsons are doing just fine, are active, and haven't seem to even notice winter so far.
