my chicks have been exposed to it for some time. But the chicks that I purchased that had an infection of it which are going to be done treatment today had it in their poo. It is recommended that I keep them separate for 30 days after the infection is cleared. But, if the others are exposed to it daily, what difference does it make if they are with the ones that might still have it in their droppings? It is already in the soil right? Wouldn't it not matter whether or not they are with the chicks? Or am I not understanding something? Please explain so I can understand this bit thank you!
