So I found a fix... We've been freezing with sub 0 temps off and on for weeks here in Utah and no frozen waterer or nipples. My setup is such that I have to have my water station outside in my covered run, not coop.
I love my Brite Tap really wanted to use it. (No open water for the girls to fling or step in...)
I know this is NOT recommended by Brite Tap or Easy Tape but it's working like a charm!
I wrapped a 3ft length of heat tape around the Brite Taps front box and secured it with zip ties. The heat tape kicks on at Aprox 38' there is a built in thermostat that needs to be placed against a pipe- so I provided a short piece of pipe. It's not pretty but the girls don't seem to bother it at all.
It doesn't get hot just warm and keeps the water and nipples from freezing. The plug to the heat tape even has a light so I know if the power goes off or the unit fails-
Been using it for a about 6 weeks, I check on it and my hens several times a day- so far so good! No more worry. No more getting up in the wee hours of the morning to carry water out to the girls!
All is well- we're getting 5 eggs a day from our 6 hens!!!
