Cauld Frosty Morning No.3

The ice was about half an inch thick on the hen's water bowl this morning and the ground is crunchy. The cab driver the other night told us this will be the coldest winter in 100 years. I'm not sure where he gets his information but I'm thinking I might construct a styrofoam surround to help the bees retain warmth throughout. Hmmm, I'll just put the kettle on and give it some more thought...
