I have an established flock of 3 hens and a roo of Barred rocks. I have a couple of 12 week old hens (1br and a mystery) and a few guinnees. I am assuming it is time to introduce them to the flock and am not sure how to go about doing this. we have been letting the two hens out to feed and the roo just beats them up. I need the brooder cause one of my hens is getting broody. I guess I need to know how to introduce the hens and whaT IN THE HECK DO i DO WITH THE GUINEES. lol The guninneea were an impule buy and I don't have a clue.
