My white rocks stopped laying after I brought 6 Americanas in

I am in a quandery: My White Rocks have stopped laying eggs since I brought home 6 Americanas. I've been watching to see if they are being bullied and find the americanas to be more aggressive then the white rocks. Help Please.. The new chickens were free range before I got them. What am I doing wrong?

Maybe they are just needing a little time to adjust. If pecking order was upset. I would just give them a little time. They will start laying again soon. Hopefully.
