Hi there - I have six laying hens (5 mthsold) that have been in a beautiful coop and run happily till now. But I have really been wanting to try letting them free range. I am nervous about the chances of our neighbours dog getting loose... or predators in the wild.. or of them wandering too far. From your experience... is it safer to just maybe make a mobile unit to let them graze (worried about burning the grass) ... or will they generally stay close to the us and the coop. I have 3 young kids so if the hens are out.. i can't always watch them as i am in and out and all about - I am worried about that. Any thoughts from others with more experience? Thanks so much!
