I wouldn't put them in with 2 week old chicks, the chicks could hurt them. I have heard that the reason they need help finding the food and water is that they have poor eyesight. I rarely have chicks in with them and never had problems. I have also heard that you can't move the feed or water or they won't find it, I never had problems with that either. For the first few days I have feed down in an egg flat. I just fill the cups up. Once they are all eating from the regular feeder too, I remove the egg flat.
I don't know what you are using for bedding, but don't start them on newspaper. As with any poultry, it can mess up their legs because it's to slippery. Feed them a higher protein food like gamebird starter, and above all else try to remember that they can be highly addictive!
