We're at -10f here and my heated rabbit bottles haven't arrived, all the stores are sold out of them, we got the wrong kind of heat tape to diy it. It's my buns first time and ours. I put in the bottom of a pet carrier for the nesting box and put in a bunch of nice timothy hay yesterday for her.
How does everyone else handle keeping the bunnies water from freezing?
A pond pump to circulate the water prevents it from freezing. Easy and cheap
