Can you post pictures of them?
I'd keep the month old chicks on the starter, let them have it in front of them all the time so they can eat when they want. If they are let out in the mornings from a coop, I'd give it first thing in the morning, and make sure they had some when I locked them up at night. Sometimes mine clean their feed containers before I let them out in the mornings, and sometimes they hardly touch it. I figure they know when they are hungry and want it.
The 4 month old RIR, I would give them a growth feed, or if the starter is a starter/growth feed like mine is, I would leave them on that.
The hen does need laying pellets.
Can you put a piece of something in the coop to separate the month old chicks from the hen? I think they would only need to be separated at night. Free ranging they have plenty of room to get away from each other if they want. Therefore the chicks could go their own way, and away from the hen.
I have 3 different age groups in my flock, with the oldest being about 9 weeks old, and the youngest being 4 weeks old. The oldest let the younger where they stand in the pecking order, but they don't constantly peck each other, or anything like that.
I will eventually free range as mine get older, but right now they have a 30'x20' run, and a 10'x20' coop.
The reason I wonder about an outside predator though, roosters that young don't typically kill each other. They give each other a peck here and there, might pull out a feather or two, and they thrust out their chest and raise their heads at each other, but they shouldn't be drawing blood, or killing each other when they have plenty of room.
