We are new at raising chickens as of this Spring. I have a flock of four (all hens...jtherebwete five but i recently adopted out our frizzle roo) the flock now consists of 2RIRs, one Buff, and one Silkie. I have raised this flock from a couple of weeks old since Easter of 2013...(end of March). I now have three Silkies hens that are still in the brooder that I've been raising since Mother's Day of this year. I am trying to intro my three silkies into the existing flock, but they are obviously smaller than the RIRs and the Buff. I have tried to put the younger flock in the backyard for an hour or so at a time with the free ranging existing flock and all goes well at first, but then the lead hen of the existing backyard flock begins an all out showdown with my newer silkies and will chase and peck the "babies" until they hide. The poor silkies seem so scared and defenseless and its horrible to watch . I have read and read about introducing them to the coop at night, waiting until they're the same size, segregating them in another pen, etc. my worry is that Because the silkies are a smaller breed, they won't grow to a similar size as the RIRs and the buff. The three are cool with the existing silkie in the flock because they have been raised with her. I guess my question is...is is possible to integrate my three newer silkies into the existing flock at all?? (I've read that it may be impossible)...oh.,.and my existing outdoor flock has begun to lay, if that had and bearing at all. I love my sweet silkies and they actually act like I'm their mama...I certainly don't want to see them hurt by putting them into our coop...but, they're in a bin and I'm afraid they're going to begin to feel stress being crowded together in the house. Please help!!! Again, I'm a totally new chicken owner and Learning everyday. I am open to any helpful suggestions I can get, Thanks so much in advance for any input!!! I truly love my chickens, especially my sweet silkies and want them all to be happy and healthy!!!!
