Well, mission accomplished. Sorry about the unholy mess. The flush was supposed to clear out any blockage in her intestines so when the mass breaks up in her crop, she can move it on down and out.
After you clean up the "treatment room", have a cup of caffeine, and the patient has had a chance to stretch her legs and relax, it's time to do one final dose of oil and a stool softener. Also, be sure this young lady has access to some quality grit. Just offer it and see if she'll take some. I know you're concerned she has a crop full of grit, but we don't know for sure, and a chicken won't eat grit if they don't need it.
Do you have castor oil? If so, use that this time. If not, use mineral oil. If you haven't got that, just use the coconut oil. But include the stool softener with it. Give it half an hour to work and then do a ten minute massage, very gently, like you're kneading a tight muscle. Keep your fingers moving around. You should feel the mass give and start to soften and fall apart.
The crop drain is about one third up from the bottom. Aim for that as you soften the mass, and push it toward the drain. Let the patient rest, and do more massage after about ten minutes of rest.
Well, no, but if you are, you’re in great company. 
I will go up to the coop and get her some grit right now. But I won’t give it to her until after the oil and stool softener. Just to make sure, I give her only ONE of the stool softeners? Is that correct, @azygous? I think she’ll gobble it up tonight. Heck, she might even gobble the coconut oil. I’m sorry, but that’s the only one I have out of the three. Castor Oil? Are you kidding? Do they even sell that stuff anymore? Thank goodness I didn’t go over my due date with either pregnancy or my MIL would have been telling me, “Here honey. Take some of this and that little baby will be here in no time!”
No thank you, ma’am!
