Need adivce. I don't want an attached run. I plan to free range girls a lot. I would like to let them out of coop in morning, but I feel like free ranging for 8-10 hours really increases the risk(can't have roo in city either). I had the idea of making a large portable run and letting them in it from about 8am-4pm and then letting them totally loose from 4-roost time. I think the run should protect them from hawks, but what about other DAYtime predators? I almost fear that having them contained may be more dangerous if a crafty predator can tip it or dig under it. We have a rare fox and stray cats and rare coyotes. We have hawks galore but a lot of tree and brush coverage. Thoughts? Is this is feasible would peck n play be safe or the PVC pipe run? Another? Thanks!
