I want to build a small coop for isolating both new birds and if my hens decide to hatch chicks. It needs to be simple and cheap, and quick to put together. Also, it would need to be pretty warm and able to accomidate a heat lamp. Any suggestions? I have 3 sheets of 4x8 USB already primed(I was gonna use it for my new run, but I can go pick up some more next weekend anyway because I need more to complete it anyway). And lots of 2x4's and screws.
