Hi and
to BYC from Kansas!
Good for you! I've always wanted to rescue some ex-batts.
Sounds like she's just chatty. I have a hen that does that. Especially if she found something cool that I need to see.
Some basic chicken noises are:
Laying Cackle: Lots of hens will announce when they lay an egg. Usually it goes on WAY longer than is necessary, and will cause any other chickens to start talking too. Although some hens are more "modest" and don't have to announce when they lay an egg. They'll just walk away like nothing ever happened.
Singing: This is what happy chickens do. It can be short clucks or more drawn out. It's thought to be a form of self-amusement. Like a human who hums while doing chores. This is probably what your hen is doing.
Contentment Call: This is a short low-pitched call that chickens use when they are moving around or foraging. Most likely it is just to keep in touch with each other.
Food Call: A short, rapidly repeated
"tuck tuck tuck" noise roosters and mama hens use when they find food.
Danger Call: Roosters (mostly) and sometimes hens will use this when they see a flying object. They will tilt their head to the sky and let out a low "buuuuuuuuuuuuurrrrrrrrrrrr" noise.
Broody Hiss/Growl: These are really the only "angry noises". These sounds should be pretty easy to identify when you hear it. The hiss is just that, a hissing noise. The growl is more of a loud moaning sound. Both are sometimes used when the hen feels threatened, but mostly when you invade a broody hen's nest.
There are really no angry noises except the broody hiss and growl. It sounds like you just have a happy talkative hen.
Hope this helps!
