I am so excited because I just picked up my first little girls yesterday, two 6-week old barred rocks. Now, it getting down to business time and I have to finish my coop and run. I am building a 3x4 coop with an attached run, much like the "playhouse" style I have seen everywhere. My question is this (and any other advice would be appreciated) "how large should my run be? Should I make it 8x3 or 12x3?
