I have one beautiful 9 month old Barred Rock rooster that crows like he's supposed to. I also have a younger 6mo old BR rooster almost full grown comb and plumage, a 6 month old Leghorn rooster and I believe another rooster that is almost full grown about 6 months old, can't think of his breed right now. Anyway none of these other 3 make a sound. The older rooster shows his dominance and runs the others off and or chases them to show them who's boss. The 6 month old BR runs on the outside of the pen and is not let in with the hens and older rooster because he's starting to run the hens and stir them up so I kept him away from the others. Are these other roosters keeping quiet because they are afraid of the dominant rooster? The Leghorn is terrified of him and won't hardly go out of the coop if the older one is in the run. Will they crow at a later age or not at all if the dominant one is around? Thank you.
