New pullets to my pullet flock

[Chickfinity]

I have 3mo old pullets for two weeks now (flock of 7). I added 2 more pullets yesterday - 2.5 mo old and 2 mo old (now a flock of 9). I know to segregate in crate, but I couldn’t help myself and let the news ones for a little - all on medicated feed. I quickly learned that was a bad idea. 3 of my hens were pecking at them so I pushed them away to protect young ones and now they are at mad at me. They will eat from my hand but then go away. Newbies are back in the crate. Idk what’s worse teenage girls or pullets . Will my older pullets let it go?

I guess the best thing to do is monitor them and slowly carefully,integrate the younger ones
