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.
I have the same problem. Fortunately it is very rare when she tries to crow. I don't have any advice on what to do. If you get some I'd love to hear it as well.
