Does anyone else have this problem? I have 3 Silkie roos that share a coop and yard with 17 Cochin bantams hens and 7 Silkie hens, however they only hang around the Silkie hens and "do their duty" with only the Silkie hens. (I have checked the Cochin eggs for fertility and they are always negative) Granted all the Silkies were raised together (I hatched them from eggs from 4 different breeders) and I introduced them to my flock of Cochin bantam hens, but I would have thought that the boys would be in heaven with all the girls to choose from. Everybody gets along fine and the Silkies mingle with the Cochins for most of the day but drift off to their own group. I have heard that Silkies will mate with other breeds but I don't know how to get them interested in the others. I know that 3 roos to only 7 hens is not a good idea which is why I would love for them to include the Cochins. Any ideas would be great! The Silkies are all around 6 1/2 months and the Cochins are 3 or more years old.
