I have a black Astralorp, Priscilla, who actually throws tantrums!
She's wanting breakfast and will make an awful racket until I come down with their smorgasbord of mealworms, porridge, banana, fermented seeds and lettuce. It's just like when children start off, "mum... mum... mum... Mum! Mum! MUUUUUUUUUUUUUMM!!!! Lol. I wonder she doesn't damage her vocal chords when she gets to the last, loud, extended baaaaaaaaaaakkkk!
Priscilla will tell me when something is not right... she is the 'neighbourhood watch'. If a chicken is over the fence (happened a couple of times), gone under the deck ... or whatever, she will let me know! I have apologised to the neighbour (with a bottle of wine) and they said it doesn't bother them (thank heavens).
All my girls announce the arrival of an egg. They're very proud and if I'm about, I go out and praise them. It usually calms things down.
Unfortunately, there is nothing you can do to keep them quiet. My chickens are never locked up in their coop. I did have to keep them inside it when the tall fence was being built and they certainly let me know they had 'cabin fever'. I would not ever lock them up other than for their own safety.
They put themselves to bed around dark and get themselves up in the morning. I used to lock them up but a series of events had me introducing one new chicken... always thwart with upheaval to the pecking order. As she was still young and smaller, I was worried that if they were in an enclosed space, they could damage her, or even kill her. So little Prudence was the reason I left the coop open, initially. We don't have foxes near where I live and the yard is fenced against dogs. I have two cats myself and they interact quite happily with my chickens.
There are snakes here. I did have one chicken die of fright when a large python draped itself over the coop door. We took the python to a nature reserve nearby (but far enough away so it wouldn't be able to return). I keep an eye out for snakes and especially now that the weather has warmed up with the arrival of spring, and if I notice eggs missing, that will be a good sign.
So, all a verbose way of saying... take a treat to your neighbour (chocolate, wine or both ;) ) and hope that your girl settles with time. Good luck with it all.
