coccsidiosus and getting new hens.

I would switch the Coxoid for Baycox (from your vet).  You will need to treat for the appropriate amount of time to be on the safe side.  Some hens are more resistant to coccidiosis than others (and there are about 26 different strains of coccidia which cause the disease).

As coccidiosis is highly contagious, and can be caught from fecal matter, you will have to poo pick very thoroughly while she is being treated.  I would sprinkle the ground of the run with stalosan F (a dry disinfectant), and leave it at least a month before  intorducing new hens.

Be aware, that while you are treating with Coxoid or Baycox you must throw away the eggs, plus any for at least 7 days afterwards (check with your vet for the egg withdrawal)

Sorry you lost your hen, and good luck with your other one

A couple of years ago i bought some 10 day old chicks who had it, im not sure if they had already got it when they came to me but it was the next morning i noticed the blood.

The chick in question did not move and looked very sorry for it self. it did however drink the coxoid solution and recovered very quickly. I was also bought the Bi-OO-cyst, i thought the supplier was trying to pull a fast one as i had asked if i could just use stalosan. I bought it anyway. The supplier also told me that once a chick has had coccidiosis they never make good chickens / layers. (Prophet of doom    However she recovered very quickly (which is good because it can kill in a very short time) and she got older and went onto lay every day.

If she isnt drinking it she wont get better, try dipping her beak in it to encourage her or if that fails i would try syringing a bit at a time. Even is she isnt showing any signs, make sure you treat her for the 7 days as directed and dont be tempted to miss the odd day as it will come back if she has it.

Be generous when cleaning with the Bi-oo-cyst as they can live in the ground along time without a host, which would mean any birds you get in the future could also pick it up.

They can recover if treated quickly.
