You've got a hen with a crop that feels like a granite egg, and she's strutting around like nothing's wrong. Classic chicken move. I know you're staring at her, thinking, "How can you be this cheerful when your chest is basically a rock?" It's maddening. But here's the honest take: impacted crops are the fowl equivalent of a stubborn stomach bug, and your girl is giving you every sign she's still in the game. She's pooping. She's acting fine. That's not nothing.
The first thing we'd tell you is don't panic, even though your brain is screaming, "Crop impaction = trouble." You're already doing the smart stuff. You cut her feed. You massaged her crop. You offered coconut oil, and she gave you the side-eye. That's fine. Some hens think coconut oil is a treat, and others treat it like a punishment. The trick isn't to force-feed her; it's to keep her hydrated and keep that crop soft. You can try offering warmed water with a little apple cider vinegar, she might peck at it if you put it in a shallow dish. Or put some plain yogurt on her beak. She'll clean it off and get a little moisture and probiotics in the process. Don't hover. Chickens hate hovering.
We'd also say this: don't starve her indefinitely, no. But another 12-24 hours of fasting while you focus on fluids is reasonable. Her crop needs time to empty, and sometimes that means letting the body do its slow, maddening work. If she's still firm and acting perky after two days, then you start to think about a few drops of olive oil down the beak, yes, messy, yes, she'll hate it, followed by more gentle massage. And if nothing moves after 48 hours and she starts going droopy, that's the moment to find a vet who knows birds. Not because you failed, but because chickens can hide illness until they absolutely can't.
What this comes down to for you, right now, is patience with a side of stubborn hope. Your hen is clucking fine. She's eating nothing and still producing droppings, that's a win, not a stall. So give her another day of soft drinks and gentle rubs. If her crop softens, you'll feel it before you see it. And if it doesn't, you'll know exactly when to stop waiting and start acting. You've got this. She's just testing your nerves, like feathered friends do.
