My 6 pullets and 4 layers enjoy a cup of cool vanilla yogurt with some oats and blueberries mixed in. I have a wild bird feeder that I fill with different kinds of thinly sliced lettuces (favorite) and chopped grapes. They love watermelon. They get grower feed and oyster shell all day. They usually get something to peck on in a clamp style BBQ basket that hangs in the run, like 1/2 crookneck squash, zucchini, tomato, sweet potato, etc. I usually have a flat of chicken salad growing on the deck for their enjoyment.
And It is a "HO-DOWN" on weekends with live crickets and mealworms every evening before they retire for evening. Hubby and I enjoy this time with our girls in the run teaching them tricks.
