I agree there is a good chance the crop is secondary. But if you can help that situation, you might have an easier time figuring out what’s going on. Not laying in months could be a clue. Is her abdomen bloated from fluid? I have a hen who drinks a bunch of water when she bloats up with fluid/ascites.Her crop feels squishy. Not flat.
She will not eat. I would have to force her.
I did give her some melted coconut oil via a syringe yesterday morning.
I think the crop issue is secondary.
I'm grasping at straws here.
