They are already out though... and since I got them today they don't know me and won't come to me. Not even with food. I just wanna make sure they don't run off
It's definitely Roundup time! You'll need to keep the new hems cooped in for a week, so they know where home is. Otherwise, they'll likely spread out and become easy fodder to your local predators.
Since they've already been exposed to your birds, you don't have to quarantine your new birds. You'll just have to keep your eyes open for health issues and hope for the best, there. You will, however, have to figure a way to divide the coop for about a week, so the two groups can see each other while the new girls learn where "home" is located. When you let your other hens out each day, give the new girls the run of the full coop, so they can get used to their new surroundings. When the first hens come back in to roost, put the new girls back in their section for the night.
Once your coop is ready, you can "funnel" the new girls directly in by building a triangle of temporary walls with the farthest point being the coop door. The idea is to gently and loosely (and without panicking them!) herd them into the wide end so they can go into the coop at the other. If you can't funnel them in, fix up a nice trapping corner. It needs to be someplace you can easily block off, like between two buildings or in an "ell." where two walls meet. You'll need some food (treats, like cracked corn, maybe?) and water already set up there, and a way to close it off. You can use cardboard boxes or some plywood, whatever you can pull together. It would help to have a crate to put them into, as well, so they don't get away while you catch the next one.
Good Luck!
