Seriously, I've heard the egg song from my hens, and I've heard that roosters will encourage hens to lay by helping them sing the song or going into the nesting box, but my rooster, who has never done it before, has suddenly starting vocalizing what sounds similar to the egg song at random times during the day. The first time, The flock was out free-ranging late in the day. No one was laying, attempting to lay, or thinking about laying. He was so loud and insistent at first I thought it was a predator warning call. The hens just ignored him. Then, today, I heard it again. About 10 a.m., but the hens were lounging in the dirt in their run. The rooster was singing a very insistent version of the egg song, and again all the hens were just ignoring him. He is a very vocal rooster to begin with, and I have some 10-11 week old BCM chicks in the coop next door (their coops/runs are within 2 feet of each other), wondering if this has anything to do with it? Is he just showing off? Teaching the chicks who's boss?
