I have a Mama-hen with 3 lovely chicks. They're 4 weeks old now. They live in a penthouse-suite next to the coop for now. During the day, they're out foraging with the rest of the flock, so the chicks are being introduced/integrated with the flock.
This is my first time with hen/chicks.
So I expect that in a few weeks, mama-hen will rejoin the rest of the flock in the coop. When should the chicks join the flock to roost at night? Will they do this on their own or do they need help? Will they just go in there and roost with them when they're ready, or will I need to place them in there one night?
