I went down to the barn today to find that my hatchingtime cage water system leaked out all 5 gallons of water through the bottom tier of cages. I checked all the nipples and attachments and everything looks ok, my only guess is that the system partially froze and expanded overnight and then thawed out? Today/last night was our first snowfall as well. I just installed a fish tank heater that I had bought, but I’m not sure yet if it’s working or not. It’s been on for a few hours and the water still feels pretty cold, but not freezing cold. Does anyone have any advice for using these water systems in the winter?
