Chicken seems to have something stuck in her bowel? Not sure if its an egg or not, what could help?

Hello, i have a pet chicken, who must be at least 7 years old, about a week ago she started walking weird and losing weight (even though she eats just fine), I don't think anything is going through? She walks in this almost upright position as if trying to push something out, but she doesn't seem to have enough strenght.
She eats fine, drinks water normally, and otherwise acts "normal", but I am starting to get very worried.
I'm not sure if it's an egg since she stopped laying eggs years ago after we started having no roosters, she kinda became the rooster, started singing, changed physically and stopped laying eggs.
I know Epsom salt baths might work, but I'd have no idea where to buy it, is there anything that is easily available that could help? My dad tried to give her oil (no idea if that could actually help).

You can try calcium citrate for a few days and see if an egg pops out. Just get the pills and pop one in her mouth. The calcium helps stimulate contractions and the vitamin d helps her absorb the calcium. Let me tag a more knowledgeable person since I have never personally dealt with this: @Eggcessive

Are you offering a source of calcium? Can you feel an egg?

Have her pupils always been misshapen? Her eye looks as though she may have Marek's Disease. I don't know whether or not that is related to her posture issue though.
