Freezing water

[ahlam1399]

Bit of a silly question maybe but, gardeners use bubble wrap and bagged compacted straw to protect outdoors plants from frost and straw..if you wrapped a barrel thickly with this (making sure horses can?t eat the straw!!) would it help stop water freezing over maybe? I can?t believe how quickly the water is refreezing in the field...smashed it at 8am this morning and by 9am putting horses out it had already frozen over again!! I am really worried that horses are not getting enough water with this being my first seriously cold winter having a horse!! Any tips or advice gratefully received!!
