Ideas for winter water bowls?

Great idea satin. We use heated water bowls

I use water bottles. I have 2 bottles per hole. I bring a bucket full of fresh filled bottles out to my buns in the morning and simply switch them out. If the others are froze solid, I will put them in my utility tub to thaw before taking them back out for fresh water in the evening.
I watch closely with extreme cold to make sure that my nursing mamas always have water available.

That’s exactly what I do. I remove the spouts and drop them in bleach water till time to go check again. I do track what each of breeding stock rabbits eat and drink year around.
