I am just getting my first chickens next week and to be honest I have ABSOLUTELY no idea what I am doing. I ordered a Radiant heater for the coup as I live in Northern MN. Now Im reading that I may not even need a heater. Since I have one now Id like to use it to at least keep my water unfrozen as well as to keep my 22 chickens a bit more comfortable in our tough winters. Has anyone ever used one of these? pros? cons? Id appreciate any advice I can be given.
