Me neither. My human raised chicks spend all day with the adult birds from about 2 weeks on and days + nights with the adults from about 4 weeks on. It's less work for me and more naturally accepted by the adult flock, and it lets the babies learn to be chickens from the adults.I have never raised chicks with a hen so I was speaking from experience with hand raising them heh.
As far as the matter of feed, while I do use some layer feed when appropriate the flock (all female, no roosters) eats whatever the youngest members eat. So that means when I have chicks/pre-laying pullets, everyone eats starter, grower or all flock.
