After getting all kinds of idea on BYC I thought I'd show you all what I came up with. My coop is for six RIR hens. It is 4x7 and has plenty of ventilation (I hope!) I don't plan to insulate bc I can put it in a insulated barn if needed. The plan is to build a bigger coop in the future and use this one a brooder. Let me know what you think, I'll post more pictures as it takes shape. Thank you for all the help so far.
