Pullet with broody hen

[Jjdesmo11]

She'll have to be integrated carefully.
Keep her in an adjacent but separate enclosure.
Maybe add the most docile older bird in with her after a week,
mix and match until you get one that will get along.
After a week of that, add another.

This might help;

Thanks so much! She’s so little so I’m worried for her I have a little frizzle I can put with her for a while. I just didn’t want to remove anyone from the coop but it’s safer than just adding her
