Well, I'm not NanaKat, but thought I might weigh-in on what works for us.@NanaKat what size tubs do you recommend for chicken waterers in freezing weather? I have too many coops/runs to have an electric one everywhere and I need a better system. Planning on going to Walmart tonight! I just don't know if I need to get long and shallow or deeper?
You folks with your calves are inspiring. Love the babies. And @bardies that boy is beautiful!
We use plastic gallon size ice cream buckets. I never throw them away. This allows you to add a little water first thing in the morning. Then, a few more times throughout the day as it freezes, add more water on top of the ice. The next morning, dump the frozen ice chunk and start over. Your tub or bucket just needs to be wider at the top than at the bottom (or the same size top and bottom) so that the ice chunk will come out every morning. I also add a large-ish rock or half brick to the container to keep the birds form tipping them over.
In the late winter/ early spring, the several ice cream buckets also make great mini greenhouses for small veggie plants on those frosty nights.
This reminds me, I need to go eat some ice cream!!
