I have 3 groups on chickens. 1st group is 8 golden comets that are 1 year old and they are my "adults" my 2nd group (teenagers) is 6 golden comets and 1 rhode island red. My 3rd group (babies) is 3 gold sebright bantams 2 are roosters and 3 red sussex. I just mixed the adults with the teenagers about 2 weeks ago. They are still getting used to each other. Last night I took the babies and put them in a pen inside the coop so the adults and teenagers get used to seeing them. The problem I have is the red sussex are getting HUGE and they kind of trample over the bantams which are about 1/3 the size. They are both 2 months old. DO I take out the red sussex in 2 weeks and have them mix in with the adults and teenagers since they are the same size and leave the bantams in there for additional time since they are small? Or should I not separate the babies at all? I do not want to keep stressing out my adult flock by introducing so many groups of chickens in a short period of time. PLEASE PLEASE help me. thank you!
