So this morning after feeding, watering, and letting the chooks out to free range I went back inside to feed my dog and conure. I had a window cracked (it was 30 degrees out, more than a crack lets all that cold in!), and enjoyed listening to the young cockerels test out their voices. But after a bit, I heard a very clear egg song! My oldest three pullets are 18 weeks old, so they are getting close to egg laying age. They are two BCMs and an Australorp (from a breeder not a hatchery), but I am not sure how long the average age for those breeds to lay it. I didn't go see who it was, since I didn't want to interrupt, but she sang for a good five minutes and was much louder than the cockerel crows! I am certain it wasn't coming from one of the boys as a "Danger Will Robinson, danger!" warning, since everyone was happily free ranging and there were no birds running back to the shelter of the coop. I did check the nest boxes later to see if there was a pullet egg, but find anything. So do pullets practice their egg song before they get to laying age? I am certain of the sound, since I've heard it before with a friend's chickens, and youtube videos (BEGAWK! bok bok bok bok bok BEGAWK! bok bok bok etc. ).
