We picked out 7 RIR's and 3 Americaunas. They grew up together in a pen with 300 other 8-10 week old chicks. We've had them getting close to a week now, and the RIR's are pounding the americaunas. The reds chase them all over the place, won't let them eat or drink, and there's a lot of feather plucking. Will they all grow out of this after some point? Or should I see if the guy will take them back and trade me for 3 more reds?
