How old is she?
When was she dewormed?
If she's acting off and has not laid eggs and should have, start her on 300mg Calcium Citrate+D3 once daily for a week.
Make sure she has access to Grit (Crushed Granite) and Oyster Shell free choice.
Check her crop to make sure it's emptying overnight, look her over for lice/mites.
It may be worth treating for Coccidiosis and Worms, the poop has a lot of mucous and looks like a hint of blood, but hard to tell.
Corid is the treatment for Coccidiosis and you can use Fenbendazole to treat worms. There are no natural remedies for either, if a bird is unwell, they need to be treated.
Liquid Corid dose is 2tsp or Powdered Corid Dose is 1 1/2tsp per gallon of water given for 5-7 days as the only source of drinking water.
Do not add any extra vitamins/electrolytes that contain B1(Thiamine) to food or water during the course of treatment.
To treat most worms that poultry can have except for Tapeworm you can use Safeguard (Fenbendazole) or Valbazen (Albendazole). Both are given orally by weight; they do not mix well with water.
Safeguard 10% Liquid Goat Dewormer or 10% Equine Paste 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.
