I used frozen peas. And @WannaBeHillBilly Ideal is a certified clean facility so you cannot go in. Even the employees have to wear shoe covers and spray themselves with disinfectant before they go get the birds. There is a technical term for this that escapes me now. But you basically get handed your birds though what looks like a bullet proof window. Also, they appear to serve more a commercial market. I think Metzers does more small orders. Think that is part of the difference in quality and price of birds. I have had so much fun with my mixed breeds, I would go back to them. But NO Magpies!!!!
