I have a very small coop for the baby chicks for now but soon I know they will need a run or "yard" to move around and enjoy the grass ect. I was thinking of putting a 4x4x6 dog pen around it with a covered roof keeping the coop for nesting, sleeping. Will this be big enough for 4-5 chickens(no roo)? I have tried to add a pic of the coop but for some reason site won't let me post the pic. will try again shortly. Do to restrictions they must stay confined. ..all suggestions helpful.
