Elaine's and my decision to keep both of our seven-month-old cockerels in our chicken run is proving fascinating to watch. When Boss crowed for the first time on September 11, we were very curious when Johnny would start. Johnny first crowed on October 2 and when he did so, Boss immediately chased after him and pecked him hard on the back of the neck.
Johnny did not crow again for several days and this time when he did so, Boss once more chased after him. Johnny quickly ran away to avoid a pecking, but he has not crowed since nor has he shown any interest in doing so.
Boss is a solid three inches taller than Johnny and is also much more "filled out" in appearance. Boss crows every morning, but he has yet to master the full "cock-a-doodle-do." The crow is more of a "cock-a-doo" then there is sort of an "after shock" and almost a grumbling sound is emitted.
Boss also has to flap a great deal to send forth his gobbles. In short, he has not mastered the art of crowing yet. But two things are definitely certain: Boss does not take kindly to Johnny asserting his masculinity, and the former definitely rules the chicken run.
