I was perscribed Batryl to treat my ill flock of bantams. The vet said I could find it at any tractor supply store but none of them carry it or have heard of it. I can't find it any where but I bought Tylan instead because it seems to cover the same things but I am scared to give it to the flock until I know for sure it is safe and I can not contact my vet until thursday. And also the medication is being ministered via drinking water. So pleas if you don't mind helping me I'd greatly appreciate it.
