Hi! I just added three chickens to my flock. I had 1 chicken and 1 rooster for about a year. Then we added the three chickens Friday evening. My one chicken and rooster were two peas in a pod, but now I notice my rooster not bothering with her anymore since adding the three new girls. The three girls do not bother with her as well and I caught the rooster tonight not allowing my girl in the coop for nightly shut in. Is there anyone who could help me understand? Why would the rooster push her out? Why won't the other three girls accept her? What can I do to help them? Thanks!
