hey its brandon ive had my 8 silkies for 3 or 4 months now they were in a chicken tractor up the top of the field until a week ago, when i moved them into the adult main coop. when can i let them out to free range over 3 acres????i dont want them going back to the old coop or getting confused and not going in, and will they just attempt escape???i have 14 other hens at the mo, and its getting difficult to keep the silkies in, so i need to know if they will be ok! thanks in advance!
