I was wondering if anyone had ever or had thoughts about adding sugar to the drinking water to lower the freezing point? you can't use antifreeze but I figured the freezing point of water is lowered by adding salt or sugar, I had stumbled across a post somewhere about hummingbird feeders not freezing as quickly or hard enough to break the glass I think the ratio for them was 4:1 probably too much for long term drinking water for chickens but a little bit might be okay for them? would a little sugar help warm them up like an energy boost maybe? I have a heater for the main coop but some like the pigeons, I have to dump ice and refill a couple times a day and same with the rabbits, I was just wondering what your thoughts might be? fair or fowl?
