Glad to hear she's doing better.
Has she been eating something red like tomato, watermelon, etc.?
I'd see that she's eating a nutritionally balance feed, provide grit (crushed granite) and oyster shell free choice.
The poop has various unprocessed bits, so they are passing through the gizzard without being ground up. This can happen, but if it's consistent, then hopefully having some grit can help.
Have you dewormed her? If not, then I'd consider doing that as well.
To treat most worms that poultry can have except for Tapeworm you can use:
Safeguard (Fenbendazole) dose is 0.23ml per pound of weight given orally once a day for 5 days in a row.
---OR---
Valbazen (Albendazole) dose is 0.08ml per pound of weight given orally once, then repeated in 10 days.
