I am making calls to the Corid veterinary department but keep getting passed around - no answer yet. I did go to that link but how do you convert mg into cc? In my research it seems it cannot be converted. The 10cc dose was recommended in an earlier reply on this thread. I administered that last night as she is a trusted source. I am only mixing up a quart at a time (only six chicks) so 2.5cc in the water. I used a syringe and put the Corid into a teaspoon to see how much it was....it looked like about a third. That didn't seem like too much, but I really don't know. I am very nervous because I recently over-dosed my dogs with a worming solution with almost disastrous consequences. I bought the stuff at the feed store, apparently for poultry, but when I got it home and read the label there were only indications for cattle, dogs and cats, and they were in drops per lb. of body weight. How on earth do you measure that many drops?! This is so frustrating as one little chick is really ailing and I don't want to waste any more time. It took me a whole day to find the stuff. Let me know what you find out. I will do the same.
