Okay. Now that I've read through the thread... this is similar to what happened to Seneca.
@FlemingFarms, don't be stingy on the coconut oil. I wouldn't hesitate to give her 2 tsps. Is she still drinking well?
You can get stimulant free stool softener at WM:
Pop one of these in her beak also.
I would continue to withhold feed until she defecates but continue to offer her as much fresh clean water as she wants.
At this point I would soak her in another warm bath for about 10 minutes then glove up (or not) and insert a lubricated finger slowly and carefully into her vent and feel for either a poop clog or an egg. If she is making the low occasional bock... bock grunt, she is straining and may be getting exhausted trying to force out what is in her.
When my hen became constipated due to her ordeal, I manually "scooped" some of the poop out of her and she was able to push out a great deal after that.
If your hen doesn't produce a bowel movement within 2 hours of the above treatment AND SHE IS DRINKING WELL you could also try giving her about 1/4 of a pedia-lax enema. Also found at WM:
I would do this as a last resort and she needs to drink a lot of water to rebalance her hydration if you have to resort to this.
