I have 2 pet Coturnix quail we hatched as a science project. They eat unmedicated quail chow, mealworms, bugs and crushed egg shells. Recently I've had 2 people remark that they look fat! Hrmph. They have a large enclosure and don't seem to have any trouble running around at all. I do keep food in their cage at all times and refill several times a day (they also flick it everywhere!) I'm not going to eat them or sell them, they're ours till they die. However I don't want them to be unhealthy! How in the world will I know if they're too fat? Do they self-regulate on food or eat even when they're not hungry, like humans?
