6 o'cluck
Da average time in da early morning when da "man of da henhouse" lets off his famous loud wake-up call.
In da infamous "which side of da barn-roof does da rooster's egg roll off on" riddle, it doesn't matter if you state dat said event happens at 6 o'cluck or 8 o'cluck or anytime in between --- roosters don't lay eggs, so it's immaterial what hour you specify dat he crows.
