Need some help, my girls (buff Orpingtons)will be 18 weeks tomorrow. I have been letting them roam the back yard out of the run, still fenced in and they really seem to be enjoying it. So with nesting boxes should I keep them in the coop or since they are roaming more leave them out of the coop? They have found a favorite bush to hang out under and I keep checking for eggs but nothing yet so just wondering if a outside nesting box would be better. Thanks all!!
