Tadpoles From Under Ice

Good news! The tadpoles appear to be ok. I broke the half inch thick ice on the tadpoles pond again this morning. A couple of hours later when the sun was out, a mass of tadpoles came to the surface. They are very lethargic and didn't dive when I took the picture. Bit I think they were enjoying the sunshine and getting their fill of oxygen. I don't yet know how I'll keep the ice off if we have an extended cold spell so I will ponder that problem.
