Hello, It is supposed to frost tonight, so I semi winter proofed my coop. I put thick painters drop cloth on the side of the coop that gets all the wind ( edge of a field) and up on top where the girls like to sleep right next to the chicken wire. I left their heat lamp on and I put a therm. in there to make sure that it does not get to hot. When I went and checked on it an hour ago it was at 72 degrees... is it ok that I am doing this? with the wind chill and humidity I was worried about them getting cold/sick and frost bite when the weather gets colder. Should i just not do this, or am I spoiling my birds to much.
