My 2y/o Blue Andalusian hen just started crowing.

That's an alarm call....sounds much like the' egg song'...
...tho males will also sing the 'egg song' along with the ladies.
The 'egg song' is actually a recall/location call.

Makes sense. He does it when the hawks are near or one hen is behind the barn where he can't see her. I figured it was something of that nature.

So, I've read about this as being somewhat rare, and also meaning a hormonal imbalance and/or a tumor causing a hen to morph into a roo, but I really never expected to have first-hand experience.

Today, while on the phone I saw my Blue Andalusian extend her neck like a roo and let out a full-on crow, THREE times! It was definitely quieter than a real roo, but absolutely a fully formed crow.

I'm really worried about her now. She's my favorite hen. She hasn't (yet) stopped laying. She laid a pretty white egg yesterday. Of course, by the time I was off the phone & ready to video it, she stopped.

She's an Andalusian so she's always been pretty bossy, but she's never crowed. She has always done the wing-drop and circle to show she means business to another hen, and she tidbits to me, but several of my hens tidbit. I had a cockerel in my flock for about 9 months (hatched him out in May of last year) but re-homed him 6 months ago. He was only a flock protector for a few months, so she probably isn't replacing him.

Has anyone had a hen that crowed and lived to a ripe old age? My girl is only two. I would do pretty much anything to see her live till at least 10.

My blue andalusian crows also. She has always been protective of her brood mates. She has crowed intermittently since she was very young. My chickens eat organic and sometimes fermented feed. They free range in a Large! backyard under trees. They never have faucet water. Berkey water for these pampered girls. I want them to feel well♡ I love her crow. It is beautiful and haunting like it is farther away. It is quieter as you said.
