I had 8 hens and 1 rooster in my chicken yard. I added 8 more hens and another rooster. The first rooster is not very happy about this and has been chasing and intimidating the new rooster. Pecking order has been established and the first rooster won the alpha position. However, it has been 4 days and the first rooster won't let the new one anywhere near the hens, food or water. Is there anything I can do to speed up getting the roosters to tolerate each other?
