Hi, I have 3 Rhode Island Reds, one of them turned out to be a roo so I want another gal but I figured I'd go out and buy a pullet around the same age (7 weeks). Does anyone have experience trying to integrate young pullets to a new one? I was wondering if it might go over fairly easy as my girls and one boy play fairly well together and don't peck at each other too much other than the roo bullying the girls a little. Any suggestions? Thanks!
