. I have a separate area that is attached to my coop, it's just a run with access to a small separate area of the coop. I put the chicks in it (when they are old enough) for about a week, so they can get used to the older girls, and the older girls get familiar with them. After the week I have a little door that I open (where the chicks can get back in, but the older girls are too big to fit). I let them out for a couple hours a day (when I can be close enough to hear/see if they get into trouble), and make sure they know how to get in and out of the little door. I leave extra food and water in the run for them, so if for some reason they get bullied away from the regular food/water they'll be okay. I leave that run open for them until they go into the "big girl" coop at night to roost and hang out with my older ones. I've never had a problem with integration.
