Histomoniasis aka Blackhead

Blackhead is caused by a protozoa. Treatment is 250mg metronidazole given orally once a day for 5 days. Then you have to eliminate the host that carries the protozoa...the cecal worm. Valbazen liquid cattle/sheep wormer will take care of the cecal worm....1/2cc given orally undiluted, repeat again in 10 days.

You seem to be really good at finding official type references. Are there any for blackhead medications that you have seen?
 
I've used metronidazole and valbazen as well as a host of other wormers.
Yes, but surely you wouldn't give a 100 gram chick the same amount as a 5kg turkey? Just looking for more detailed info...

I had a chick hatch on 6-23, died on 7-8. UC Davis confirmed that cause of death was histomoniasis. Weight at time of death was 70 grams. I also just lost a 1kg hen and I believe that her cause of death was histomoniasis. Just trying to get a handle on what seems to be a real problem here.
