Could you imagine letting them loose in the produce section of a place like Whole Foods if the setup was such that your six girls could get to all the fruits and veggies. Like when stores cut some of the melons in half and sell them that way. But in this scenario the melons would not be covered in cellophane and the kale and other tidbits like peas would be all in reach. Then while people are shopping and just going about their business you'd have Peek, Poke, Harley, Pepper, Abba and Mocha just free ranging in there.
I think that would just be duck heaven.
