I need to dose my birds with tylan 50 (shaking heads) but am confused after a bit of research on the web. What is the dosage for rir chickens if injected? What is the dosage if given orally? And finally, what is the withdrawal if injected and when given orally. There is so much info out there but it gets so confusing, thanks for your help!
