Installed a little heater!
This is the combo brooder/heater we picked up to get ahead of potential severe cold nights. Last year we installed a little sensor inside that helps us keep an eye on temps and humidity in the coop. They did ok last year without a heater but we did some tarps to help insulate. So now this year we can switch this on when it’s hitting the low lows. Might still do the extra tarp if needed.
