Well i have heard all kinds of numbers, mainly 2 tsp per 1 gallon of drink water how many CC/ml does that equal out to. and how long? 7 days? or 21? a few are much smaller then thier hatchmates and are not growing/ occastional bloody poo so i need to get them straightened out. Also will they always have the disease now? just come out of the symptoms from it?? should these birds not be used to hatch eggs from this summer?
