I grow a lot of vegetables much more than hubby and I can eat. Since the birds like to scratch around and forage, I pull out some of the plants, and give it to the birds. I eat the broccoli but give the birds the plants and they peck at them until only the plant stalk is left, the same with the cauliflower, brussel sprouts and other greens. When my lettuce starts to bolt from the heat it gets bitter but the birds will consume it. During part of the season when the garden isn't going I get nice green alfalfa and the birds will pick off the little green leaves. I can let them out to free range in our pasture but there is more shade in their pens so they may come out for a very short time but go back into their pens which they have destroyed any grass that was in them.
