What’s wrong with my chicken?

[BawkBawk123]

My buff orpington, who is 5 years old, isn’t acting herself. She stopped laying eggs, but we think it’s because she’s old. However, she’s been really sad lately. She was the one who always acted like a male and tried mating with the other hens. It’s common for buff orpingtons do this. However, she stopped when we got a (baby) rooster. Is she sad because now there’s a rooster who took her place? In addition, she has been really pale and not very active. She sits and stands in place a lot. Also, she does this thing and it looks like she’s trying to poop, but nothing comes out. Does anyone know what that means?

If this behavior change has been apparent for a significant length of time, your hen may be suffering from a chronic disease such as reproductive cancer, a reproductive bacterial infection, or internal laying.

This isn't a diagnosis due to the impossibility of determining what is wrong from just your single paragraph.

Thank you for the comment. I’ve added some more information if you want to look back at it again.

That recent edit provided a huge clue! It's one of the red light warning signs of a stuck egg or a stuck collapsed egg.

It should be treated as a medical emergency, A warm water soak in Epsom salt is the first step to clean and soften tissue and relax the hen. Calcium supplement in the form of a calcium citrate tablet is the second step.

Are there signs of raw egg on her vent feathers?

Have you checked her for lice and or mites?

Also can you take a short video of her and upload it to YouTube?
