Adding Asil kulang hens to flock.

[GhettoRoo]

Hello. So i have 52 birds from which one is muscovy pair. 4 roosters and all other is laying hens 2-2.5 kg
Im interested how these temperanty chickens would adapt?
Why I want them:
Good brooders.
Mby great flock defenders.
Wanna mix my buddies, roosters, with them to get great offsprings.
Mby they gonna stem my muscovy pair, which can be unlikeable, + drake is trying to mate hens, and I had seen hens trying to defend each other. So kulang hens could do It better.
Kulang Asil rooster probably cant live in my flock with 4 more roosters..
Thanks for reading. Advices?

Also, how would that affect them if they would add in age when they are last in pecking order without chance, or add only when they would dominate everyone or add when they're evenly.
