I haven't seen a single suggestion of having a fecal sample read, nor did I read that you did so.
You don't know how to treat if you don't know what is wrong.
I once had about 4 hens in a flock with really bad diarrhea and messy butts and suspected roundworms. Rather than worming, I had a fecal read.
There were no worms but they had a bad case of clostridial bacteria infection. Vet gave me dosages of tetracycline to treat the whole flock. Cleared everything up.
Other than warmth, ventilation, hydration and nutrition I'm not a fan of any treatments till one knows the problem.
