I had no luck last year. We had 100 heritage breed meat birds free ranging and they absolutely decimated the garden. We put up a 3' chicken wire barrier around it and they pretty much laughed at it as they flew over top or got close then climbed the rest of the height. They liked the peppers and tomatoes most but I'd say it was all fair game. We got VERY little from that garden.
Any clues on how to stop this?
I've considered just wrapping each individual plant in chicken wire supported by a tomato cage this year. Maybe that would do it.
