When a chicken is left to it's own devices, they will forage like there is no tomorrow. They enjoy eating every bug and worm they spot. So forget this nonsense about "vegetarian" hens. They like their protein. They will also eat seeds, berries, snails, grasses and other plants. In the coop we feed them laying pellets, but they really enjoy their time out in the yard.
We did finally name them all (yes I am getting a little attached). The brown one above is Lovey and she is very sweet. The brown and white one below is Goldilocks (guess who named her). The black and white one below is Petunia and the black one is Obsidian. I figured we could have a little geology lesson built into the naming project.
