The five goats behind me are MUCH, MUCH, MUCH louder than my MANY roosters!
My MIL raises goats (20-30 at any given time) and lives about a 1/4 mile away from us, we hear them ALL the time, she does have a rooster that we can hear if the wind is blowing right. We have 14 pullets (including a very vocal cockerel) and she says she can't hear them at all.

My FIL (who lives about the same distance away, but not in the same residence) has chickens and we can never hear them.
