This is the first year my rabbits will be outdoors and already their water is frozen. I cannot afford a heated self watering system (yet) and will have to come up with other solutions for this year at least. Description of my rabbitry: 6ftX12feet chain link dog kennel with black roof and solid door. Heavy oilcloth tarps (20oz) on three sides, one 12ft side backs up to garage. 10hole/2 level. I currently have 8 rabbits that use 32oz water bottles. I was thinking about rotating bottles once or twice a day. Yesterday the water froze in about 3 hours (not completely, but enough so that the spout didn't work anymore). I was also thinking about getting some heavy clear plastic to line the rabbitry on the inside, and bring in a heater or some sort. Maybe heat lamps? Worst case, I can hang the hutches in the garage like last winter, but I'd rather not. What are your solutions? Thank you, I appreciate any ideas or advice.
