I am trying to figure out what to do with my chickens. I have two coops, one is a walk in and the other is a 4X4 box like thing. The smaller one would be hard to use a light in for heat or lighting. I live in Utah and it has gotten down to 20 (as of 7am) one morning. I have no clue if it was colder in the night. It will get colder in the coming months. THis is my first winter with chickens so I am learning. I know they will eat more in the cold to stay warm but should I put a lamp in the bigger one for warmth? If so what kind? A red heat lamp or just a normal bulb? Should I do both but one on a timer for light? Any cold weather chicken owners out there? BTW, my coops are NOT insulated.
