Feels like chicken has a mass stuck in her, if she's not egg bound what could it be?

Thank you. I don’t have a thread about this hen, though she has had a lot of issues over her short life. Her crop was still full this morning, only a small amount of very bad-smelling greenish sludge poop overnight, and the mass is still hard in her abdomen. It’s not squishy, but rather feels like an eggshell. In any case, I can’t reach it when I examined her vent. I gave her olive oil yesterday with a syringe, plus three warm epsom salt baths. I don’t think we can solve the crop issue when she’s unable to pass poop, so I think we’ll have to cull her today.

I'm sorry that's she's not doing well.

I agree, if you do put her out of her misery, taking a look afterward can sometimes reveal what was going on. Even if it's not a formal necropsy like you would have by sending to your state vet.
You can take photos if you wish and post them, we may be able to help i.d. some things, sometimes not.
