I do raised bed gardening, mostly 4'x8' boxes, but a couple of 4'x4's. I have this idea since I'm so stretched for time and I can't get my kids to weed well and reliably, that I will put the chickens to work this fall and again in the spring before I plant. Prolem is I can't let them free range the garden areas as its not too far from a shared driveway and its on the side of the yard the dogs stay in. So what I have in mind is some sort of portable collapsible chicken run that I can leave out by my garden and bring the chickens down to work the beds periodically before planting and after harvesting. Anyone have any good ideas? Also am I correct that I would need to remove all of my tomato plant stalks & leaves before they do their work because they are harmful to the chickens? Is there anything else in a typical garden they shouldn't munch on?
