Lets all get along

I have an older red hen that doesn't seem to want to have anything to do with the younger ones. They are white and twice as big. They have been seeing each other they the fence, they even stick their heads thru to each the scratch feed. But if I try to put them together she just chases after them. One of the younger ones has started to lay; I don't know which. My problem is winter is coming and they are going to have to share quarters. My little red hen is a rescue, she was found wandering, no one claimed her so I took her in. Any ideas?

Do you have them in separate coops and runs right now?

If so, you could just exchange the coops and runs for some days and then try again.

How long have they lived like this?
Chasing is normal.
How big is your coop and run?
Dimensions and pics would help immensely here.

Meanwhile, here's some tips about......
Integration Basics:
It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.

In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can really help. Lots of diversion and places to 'hide' instead of bare wide open run.
Good ideas for hiding places:
