I have 2 ft garden fencing around my kale & carrot patch to protect it from the girls when they range there. Only once has someone flew in…DH came out the back door quickly and she got startled.
I wouldn’t trust it to hold them all day…but they only go in the garden under my supervision so an hour here or there, and surprisingly it has worked (mostly!) The kale is safe!
I did leave a few spent plantings around for them to eat/pick at, and with the weeds and sunflower seeds that fell under the leaves, they have plenty to keep them busy and out of MY food.
