Had the same problem, but with just 3 domineques. Bought some amprol and had to figure out how to adjust the dose from a 55 gallon drum to drops from a syringe. 1 was too far gone and I had to uthanize it. The other two are fine now, thriving like you won't believe! I made a organic milk and oatmeal dish with the amprol in it and the scarfed it down every single meal! Also was in their water! I think it came from my garden where I put them in to get the "feel" of free roaming, it is where I put some of the other three RIR poop. They are full grown and have good immune systems, but exposing the chicks at week 1 or 2 is not good in my opinion! I won' t do it again. God luck.
