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.
Hens go broody when you don’t want them to… and won’t go broody when you do.
