They are certainly known for snagging a fledgling or two when given the opportunity. You can order frozen thawed baby quail, especially young button quail, from at least one company. I'd have to do a quick google search to remember which one. You might be able to find it on your own. Unfortunately that doesn't solve the problem of cutting costs. I would just buy mice in bulk to save money, especially when your snake an adult. Mice can be stored in a decent freezer for 6 months to a year without worry. Perfect Prey offers smaller bags of mice for decent prices.
