I have 28, 4 week old Cornish x. Yesterday, I noticed a little blood, but not much. Today, there are some more droppings but I cannot figure out which one it is. It almost looks like worms, but with watery blood. The blood on the other droppings are watery too. All of them are up and running around, drinking and eating fine. They have been on medicated chick food from the beginning too. I tried getting Sulmet today but my local TSC they did not have any. All of the stores around here only carry Duramycin. Could that work?
