my hen is behaving oddly. i cant describe in the title

[InducedAgate]

Okay so she is a buff orpington, and she's about 2 years old? I don't know exactly because I got her from my uncle, but she still lays regularly and seems generally healthy.

For the past two days she's been sitting in the nesting box, but hasn't had any eggs to sit on. When she's not on the nest box, she walks around with her feathers puffed up, and on occasion she will flap her wings and, like...scream?

She doesn't appear to have parasites and they were de-wormed recently. She also does not seem to have any respiratory problems.

She seems super angry? I don't know if she's just broody or if she has a stuck egg or something. I've never seen this rip

Sounds broody. They will sit on air if they don't have eggs. If you'd like some chicks slip some eggs under her. If not, it's better for her health that you break her of the broodiness.

ah okay okay that's what I thought
I tend to overreact a bit when they start acting super weird, and I've never had an aggressive and persistent broody before

just needed a second opinion thank you < 3

edit: this is the scream she does not seem happy
