Good morning! As I have been reading older threads about adding chickens to an existing flock, I haven't been able to answer my specific dilemma. I'm hoping some of you might be able to help me! My original flock was 8 birds hatched May 14 of 2013. Due to an overactive hawk population, I'm currently down to 3 birds. Now that I have remedied my predator situation, I'm ready to add 5 birds back in. The current three ladies are 12 weeks old, and a local farm has some 12-17 week old chicks that I can purchase directly. 1). Since the new birds are a similar age, but slightly older and will be more numerous than the existing ones, does anyone foresee problems with just adding them into the coop? I'm not imagining that my current girls would be willing/able to take out 5 new, older ones. 2). While we're in the yard, I still let my girls free-range. We hatched the current group ourselves, so they're terrific at knowing when/where to go during the day and at night fall. Will the new birds simply learn from the old? Or should i keep the new ones in the coop for a week or so and not let them out? Keep the new ones in and let the old ones out? What's the proper protocol here? Thanks in advance!
