I know I'm still learning too, but have mine on ff, and have been checking and refilling as needed starting around 645 am. I check every few hours, and towards the end of each serving they are all scratching about. Figure it is good for them to learn to scratch about a bit. They are eating out of pie tins until they get a bit bigger. I give them one last tin around 7 or 8 and since most are sleeping that lasts through the night for those wake up for a snack. They aren't starving in the morning, and all are doing well so far.
