How old is this bird?
Any chance for video?
Had a 2-3yo hen crow for a few months over winter break.
Duets with cockbird every morning then she stopped when she came back in to lay.
My Lilly does it on rare occasions. So it is hard to catch video but you can hear her in this video. She is alpha hen is over 6 years old and lays 1 egg a month which she did yesterday.
Here is Lilly.
