I have had chickens for over 40 years and have never had a rooster say "good night" before.  Every night when I shut them up for the night I make sure they're all in the little chickens house.  After I close up the house and then the pen my brown leghorn rooster crows loudly one time.  He and his 5 hens free range all day and I swear it is like he is saying, Good night to me.  Sometime it is very dark and other times it is moonlight, but it is always one crow.
