He who crows first...is on top
Roosters are infamous for their early-morning cock-a-doodle-do, but a new study looked closer at this behavior. Turns out that the first to crow is the dominant rooster in the bunch. If you take him away, the next in line in the pecking order takes over those wake-up alarm duties. But the subordinate roosters always waited for the boss to crow first, even if he did so later than usual.
