Impacted crop day 4

[Abauman]

My chicken has had an impacted crop for going on four days. The first day I was able to massage it break it up. She did have some of that expelled in poop but now we’re kind of at a stand still. And she’s mostly pooping urates. I’ve been massaging. I’ve given her oil, I’ve secluded her not given her food, but there’s still a gritty substance in there. I’ve seen people made their chickens throw up, but I’m hesitant to force feed her water, but I’m worried she can aspirate. Also, I don’t want to have her aspirate if I make her throw up. I’ve also seen these braw things, but I don’t know if she’s a candidate for those since she’s still has that gritty substance in there. I need help any advice I would greatly appreciate.
