Rainer is correct, no question about it. You have never seen a snake feed until you offer quail. so many benefits, where do we begin. I have never seen a quail regurge! Unlike mice and rats that swell while being digested, and can cause a regurge, quail are easily digested, no tough hide. quail feathers contain lots of pigment which definately is being absorbed by the snakes and producing bright red, yellows and oranges that are not produced on mice or rats. The colors are produced, just like the absorbtion of carotenes from carrots can produce orange colors in animals that consume them. I thought melanin was at work, but melanin can only be absorbed by the animal as black, no bright colors. The bottom line is this, you are what you eat. It takes a much more complex diet to raise a quail than to raise a mouse, therefore a much more nutricious feeder animal. Have you looked at the label on your feeder animals food bag. compare it to a qamebird feeder. Hey even feeding mice Chicken layer pellets, they will have larger litters than the norm., because this diet is catered to a breeding female chicken, you can imagine the effect it has on mice and rats as well. Nutrients, lots of them, and getting them into your snake in a 100% safe manner, NO supplements! Scott
