I'm having this same problem. I introduced 2 hybrids into a flock of 3 and they spend their day hiding in a nest box and the older hens take turns going in and attacking them.
Would be good to have an update on how yours are doing. I withdrew the 2 and put them in a run along side the other run so they can see each other, but I might try seperating the top hen and reintroducing the new ones to the other 2.
