There is no LD-50 for poultry because it is not approved in the US for poultry. We can't use it for meat and eggs for human consumption. It is because we don't intend to eat our Peafowl or their eggs that we feel safe using toltrazuril in the chicks for treating cocci.
While all that is mostly true, Corid is a very poor option for peafowl. Corid works by starving the protozoa of vitamins essential to both it and the developing chick, the chick does not have time to recover by slowing down the rate of increase of protozoa. You can actually kill and clean out...
Cocci usually does not bother chicken chicks like they do peachicks. It is more likely a bacterial infection, I would give one drop of Baytril orally and repeat if no progress is made within a day.
In areas that are bare dirt or sand and inside the metal brooder coop on concrete I use a pear burner or weed torch to kill cocci and worm eggs. It can be a slow process but if you heat up the concrete or dirt hot enough you can kill everything even below the surface of the dirt. I also clean...
It wasn't pokeberries that made your peahen sick. Pokeberries are actually good for birds, we have them and our birds eat them all the time. We even cut down the big branches and tie them to the pen walls for the caged birds to eat.
It is so frustrating to go through that, I know. There is just too much internet (mis) information out there that is hard to battle. The links to prove the effectiveness of sulfa drugs should help. I, for one, will not recommend using Amprolium in peafowl ever again.
That is why my vet sent these links to me and suggested that I use SulfaMed-G since the Corid seems to not be working. One of the articles states that amprolium does not work well in game birds and sulfa drugs are the better choice.
That being said, and to my dismay, my math was off by a...
Cocci, the never ending battle. Here are a couple of links my vet sent me that I found very interesting.

I am on my way out to collect samples from all pens and will run fecal exams this evening. I did notice that adjacent pens had some runny stools so I started all pens on Corid at 2 tsp per gallon. I am suspecting foot traffic has spread it from pen to pen.
