I have no electricity and my horses' water freezes in winter faster than I can keep it thawed. I dump two large buckets of warm water in it morning and night and it still freezes through to about 3 inches deep.
I have tried moving it indoors and it does help a little but we have an all concrete barn and the cold goes right through it. Electricity is not an option and we only put the kerosene heater in the barn when temps drop really low.
I desperately need help on what to do. Are there any special (non expensive) buckets I can buy/make? (I am all about cheap DIY). Anything I can put into the water? ANYTHING!! I am willing to try to make it work.
