I like to wait until about two weeks. Even at that problems arise. I had a gal buy three two week old Cameos she picked up here. A few days later she called and said two of them died, I told her no problem drop by for some free replacements. It wasn't until after I had given her the second chicks that she told me she had given them scratch grain. They had no grit in them and all she was feeding was grain.that's how I do mine too.
