For some reason our chickens have never bothered our vegetable garden (knock on wood). Flowers are another story, they will eat every new flower and flower bud they can get to, and wildflowers too. I think its the location of the vegetable garden. It's out in the middle of a field, there's not really anything close they can use for cover except the garden itself, and I think the roosters will just not let the hens go out there. We planted tomatoes, peppers, and ground cherries last year. We had more problems with groundhogs than anything. Our chickens aren't real crazy about tomatoes anyway, so that may be another reason.
