Ok, it is getting colder at night now..we got down to the low 30's which I think is still just fine for everyone. However, I'd like to get something into place for the winter IF we are going to do so. 1. We are located in MN...on the MN /ND border about central state...we easily see -40 wind chills, temps, etc. Should we be planning to heat the coop on these sorts of days? What do the rest of you in MN do? 2. Easiest, best way to keep water from freezing? we use a 3 gallon waterer that we got at Fleet Farm...I need to find out if there is something we can put in that to keep from freezing or should we get something actually meant to water chickens in the winter? Thanks!
