We will soon be building the run for our 30 RIR's that are coming tomorrow (wee one day old chicks!! Soooo excited haha). We had initially paced out a space around the coop that would be roughly 700-800 square feet. The coop isn't huge (10x12) so wanted to make sure they had lots of outside space, should we go more? Is bigger always better, or is there a point at which this isn't true? We can have nasty winters with short daylight hours, will they still want to be outside most of the days?
