I finally got the stuff I need to treat cocci, but the only thread on here gives the dosage per metric water measurements. The vet gave me these huge syringes and said to use 1/2 syringe per 5 gal of water. The question I have is this: does it matter what age the chickens are??? (Vet's closed, can't call) I have 20 wk, 14 wk, 11wk and 7 wk in the same coop. I'm worried that the dosage might be too much for the chicks, and like an idiot I forgot to ask. The vet said it's very easy to OD on aprolium. Does anyone know??? If so, pls give me the medicine measurement in either ml or ounces per american water measure. Thanks!!!
