Hi i am wondering how to add a new young rooster to my established flock of 9 hens mostly reds 2 bantams.We put him in about 2 hrs ago and the pour little guy got beat up pretty bad so i had to put a seperater in coop to keep them apart. How long will i need to keep them seperated ? I didnt realize they needed a slow introduction i guess? thx ahead of time for any help! Victor
