My backyard hens are doing well in the summer heat, although they get a little pissy in the late afternoons. I've been letting them eat around the edges of my vegetable beds. This adds a healthy dose of kale, mint, and oregano to their diet. Their favorite snack is still a handful of meal worms, though. When it gets over 100 degrees, I usually take a shallow pan of ice to the hens. The ice melts quickly, but the water is cool and refreshing for the ladies. Gladys likes to stand in the water and cool off her feet.
