There are loads of great articles here on BYC! You will want to quarantine them inside your house to make sure you aren't bringing any diseases and pests to your girls. Once you're done with that, here are the basics to a successful integration:where can I learn to integrate them? I'm a new chicken parent.
Start with a 'see but don't touch' setup. Put your new girls in with your old girls, but behind a wall of hardware cloth, chicken wire, welded wire, etc. This way they will get used to each other's presence without being able to hurt each other. Put feeders and waterers next to the fence line so that they get used to eating/drinking together.
Before you let them interact, put the old girls in the coop and rearrange the run. Move things around and add new things to distract the old girls. Then let the new girls explore and get used to their surroundings. Make sure that there are places for new girls to hide without getting cornered and trapped. Add more food and water sources, preferably out of sight from each other.
Supervise their interaction, but don't interfere-they will work it out. Unless they're holding each other down and beating mercilessly or drawing a lot of blood, they'll figure it out. If bullying issues arise, separate the bully, not the victim.
