For 10 years now I've been flip-flopping my garden and my adjacent chicken run on an annual basis. This years run was last years garden and vice versa. I normally have 10-15 hens. Each area is 40' x 40'. I have a small coop built on a cart that I can move around. I use electric netting surrounding both areas to protect against foxes, raccoons, and woodchucks. No netting on top. Hawks have not been a problem. Owls are a big problem, and I finally bit the bullet and bought an Omlet light operated door to close at night and open in the morning. This save s me from having to open the coop door early and close it late. And if I forgot, the owls, who apparently are permanently on standby, would walk right into the coop for a midnight buffet. This years garden is always fertilized, relatively weed free, and the gravel rocks are scratched to the top. Best of all, I throw any composting materials into the chicken run. The hens either eat it and poop it out as fertilizer, or scratch it into ready made compost. No muss, no fuss. Works great, best of all worlds.
