I am from Pakistan.I bought three chicks from local birds market.According to my experience I supposed that I had two hens with a rooster.Things went on well.I reared all of them.I came to know that i had two roosters with a hen.So i went to market and bought another hen.She is not adult hen.I keep her in another cage inside the original coop so that they can see each other. It has been a month she has yet not been able to assimilate in them.I have tried several times but no result.I have also put her with them at night,the roosters seemed to accept her but the hen want to peck her even at night only with the help of smell.In the day when I put her with them,the roosters give her importance by doing chicken dance around her & trying to mate with her but cannot do so because she is not adult.But when the hen pecks her she makes to much noise & the males chase her & peck her until my interference.Please help!!!!!!!!!!!!!!!!!!!!!!
