Integrating younger smaller pullets

[btegu]

I have 6 eleven week old pullets; 2x barred rock 2x midnight marans, 2x cinnamon queen. I added 2x whiting true blues that are seven weeks old. The 6 have been together from the start. Currently they all roost together.
During the day the true blues stay in the coop until the others lay down to rest before coming out to do their own thing and basically stay separate on opposite sides of the run. About twice a day one of the 6 will chase the little ones then all 6 join in and chase them around until they retreat to the coop. If the big ones stay resting the little 2 eat and drink but if they are in the chasing mood they keep them away from food.
Currently the true blues are about half the size of the others. Are they OK to stay like this or should I do more for the little ones? I’m debating keeping them back inside until they are larger or adding hiding spots for them in the run.

The younger ones are well old enough to be outside, so no reason to bring them back in.

Is there only 1 feeder and 1 waterer? I'd add at least 1 more of each, along with more clutter, so the younger ones have a chance to eat in peace and hide if they need some relief from being chased. https://www.backyardchickens.com/threads/a-cluttered-run.1323792/

Welcome to BYC.

Multiple feed and water stations and run clutter to allow chickens to hide from each other are a good idea during integration. Make sure that the birds at one feeder can't see the birds at the other one.

Chasing and mild pecking is OK, but injury is not.

More space in run would be good too, looks pretty small for 12 birds.
