Hey guys so my coop is about 4x4 ft which for two chickens I think is pretty ok right?? And my run is only 6ftX3.5ft which I think is too small..should I just let my chickens free range or build on to the run? I don't know if they associate the coop with home yet and am afraid they won't come back if I free range them. I've had them for about 4-5 days now..what should I do?!
