So I want to get some chickens to do some of the weeding, fertilizing and general cleanup in the annual veggie beds. Here's the problem: the only way I can see to use chickens and keep them contained in a safe environment, is to use 3'(1m) wide beds in long rows, which run perpendicular to their run(and the run being attached to the mini-orchard).
The large rectangle on the ground with the circles is the mini orchard of mostly citrus(I'll be doing a lot of transplanting this winter). The 5 beds are 21'(~7m) long and 3'(1m) wide.
If you notice on the pic, the closest bed shows what it would look like with chickens being allowed into it to do cleanup duty, with the other 4 being closed off to the chickens while production is going on.
My problem is this: I really like the look of keyhole gardens, but they don't seem to lend themselves easily to chickens, or should I say to fencing. Does anyone have a working example of keyhole/mandala gardens with chickens only being allowed into certain areas of the vegetable garden at a time?
I should add that this is a suburban back yard with possums, the odd raccoon(been a while since I've seen one of those) and the possibility of stray dogs. So I want these chickens protected as best as possible while they do their work. These chickens will be treated as pets.
