Yeah, i have fed them chicks and quails. But not until they were much larger. Rosey is pretty handicapped when it comes to eating quails. She cant grasp the concept of wings and spends like 30 mins eating one lol. Vicky and Caesar are poultry pros and down them pretty quick. Havent fed Gina, Louie or Luna any as like i said, they are still on weaned rats so even a baby chick is going to be too big.
And yes, boas are not picky. Mine eats anything you offer.
