I am using an approach with a group of roosters where their destructive forces they put on vegetation is put to use. The roosters are housed at night and most of most days in a 10' x 10' chain-link dog kennel. There destroying of vegetation is a form of weed management preparing ground for gardening next spring. The approach is used after the growing season where vegetation is not able to grow back before I can employ soil remediation. The pen is periodically moved to new ground. Moves are short and orientation of pen is conserved so roosters can figure out how to get back in. When roosters are out during the work week, it is only for an hour or so just prior to sun down. On weekends and holidays they are released at dawn so they get at least two whole days of free-range time per week.
There are places I do not want them to visit while in free-range mode, namely the poultry yard and the road. Feeding stations and cover patches get their attention in an area that is roughly 2 acres. The area is also patrolled heavily by dogs and even my kids so predator issues are not a major concern.
A pair of game chickens also occupy the same range and managed in a similar manner although they are housed in one to those rather flimsy prefabricated coops that has been mounted to a sled so I can move it as well. The coop is moved in parallel to the larger dog kennel. The game rooster must be placed back into coop by hand each night, otherwise he would roost on the roof.
Free-range time help the chickens get their greens-fix and provides windows for me to move their containment units.
