I understand about keeping chicks separate until they can stand up for themselves. I'm not really sure what you can do then, unless you find some safe shelter for them at night.
Sorry I'm not much help
Thought this might help - made a list of all the names :) Silly and otherwise!
Sheep, Murphy, Lambchop, Mutton chop, Ovejita, Ralph, Ducky, George, Meri, Overo, Shark, Kris Kringle, Puddles, Puddle jumper, Clarence, Rupert, Benjamin, Wolf, Moony, Murray, Finnegan, Patty, Albert, Fred, Patrick...
Your advice is pretty sound. I'm personally wary of fruits and veg and meat but carbs and things are surely fine. Or you can throw it out and the wild birds will finish it off.
