Question for you all. I live in central Illinois, so we have some really cold winters, but randomly warm days as well. Trying to figure out my water. Right now I have a plastic bucket system with four of those metal nipples on the bottom. Would it work to use this with a heater dropped in that is temp controlled? Will the bucket end up cracking? Will the nipples freeze and not work properly even though heated? Also, my water and food is outside, and not in our coop. On the coldest of days, do you put yours in the coop or continue leaving it as is? TIA! This is my first winter with my chickies Edited to add more info: Our water bucket hangs and is impossible to knock over, and the way our run is set up the cord would be impossible for them to bite because it comes in from the top and isn't really exposed to them or snow. There is a lid that snaps on the top. There wound be like a 2 inch part exposed as it comes in from the top and enters the bucket, but that can be problem solved. The heater I'm looking at is a drop in, much like a fish tank heater. Does anyone have any experience with nipples freezing...because I like my hanging bucket system as it is impossible for them to knock it over.
