My black copper marans hen was sick about a month and a half ago. She had a poopy butt, downward pointed tail, lethargy, and wasn't eating or drinking (original post:

With y'all's help, I got her feeling better, eating, drinking, and back to her normal bubbly self. However, the poopy butt still hasn't gone away and she has not laid any eggs since being sick. What should I do to get her back to normal and laying again?
You're other thread is quite involved and has very good information.
I'm glad she's feeling better. It sounds like she's doing well if she's eating/drinking and back to her normal bubbly self.
Some hens have a poopy butt that needs to be cleaned frequently. Perhaps they are very fluffy and need a trim. Could be they don't expel as forcefully as they need too, so may factors.
If you have not dewormed, it may be a good idea to do so. If possible get a fecal float and see if it's necessary. If vet care is not an option, then deworming her may be warranted to see if it helps with the loose poop. More info about deworming below.
Check her for lice/mites.
As for getting her back to laying, that would be up to her. On your other thread, just a quick scan, she may have had something reproductive going on (?) which is often the cause of a laying hen to start having symptoms of decline and not feeling well.
Either way, you cannot make a hen lay eggs, her reproductive system and body dictates that. If she's happy within herself and interacting with her flock, then enjoy her.
To treat most worms that poultry can have except for Tapeworm you can use Safeguard Liquid Goat Dewormer or Equine Paste (Fenbendazole) or Valbazen (Albendazole). Both are given orally by weight; they do not mix well with water.
Safeguard dose is 0.23ml per pound of weight given orally once a day for 5 days in a row.
---OR---
Valbazen dose is 0.08ml per pound of weight given orally once, then repeated in 10 days
Here's how to give oral medications:
