I had noticed my sheep weren't drinking much in the past few weeks- I was always emptying the frozen tub and refilling it but the sheep wouldn't drink. I splurged and got a heated cistern for them and while they were curious about it, they wouldn't drink. As I was cleaning the tub, I realized that our spring water + a heater made the water smell like a fish tank! I've been dealing with urinary calculi in the male, I'm sure the female has them too but she's able to pass them, so keeping them hydrated is very important. I've been bringing buckets of house water up to them, but they are not interested- they'd rather eat snow. As per the vet's suggestion, I'm not bringing *warm* buckets of house water up and the male will occasionally drink it but the ewe will not. I'm really stressed out worrying about their hydration. How much water are your sheep drinking in the snowy regions? Have any tips on how to get a sheep to drink? Thanks
