Hi! I was wondering how much space a bantam needs? I have a coop-run I built a few weeks ago that is about 8'x5'. It has the coop part built into it (2'x5') so that leaves a 6'x5' run part. I will be moving it a few time a week because is is built like a tractor. tomorrow I am getting 1 self blue bantam, one mixed bantam and if there is enough room 1 more self blue. Thanks!
