Hey y'all I'm looking at trying to set up a new watering system for my flock of around 30 birds. I bought the chicken nipple this summer and my ladies and roosters refused to use that system, I tried it several different ways. I'm looking now at the automatic system here: https://m.www.mcmurrayhatchery.com/automatic_water_bowls.html But I'm trying to figure how to keep the water from freezing (in PA in the cold cold mountains). Their website doesn't offer any subtle ideas so I emailed aand asked what they recommend as they manufacturers but what do you ladies think? I'm planning to hook it up to a large trashcan sized water container and in the nipple system I was going to us a medium pond heater in the water holder but the hose going to the bowl is small and it looks like it would freeze easily. I can't wrap it caught the ladies & gents will tear apart anything I use (I could wrap it and then cover that in a pic pipe...). Alright what do y'all think?
