I have a new batch of chicks arriving tomorrow.  But yesterday I think one of my chickens just died of cocci.  I'm treating the other seemingly healthy w/ what I could find locally (liquid sulfa-nox).  Do I treat the new chicks right away too?  They will be exposed to the same soil as the other chickens soon.  Do I wait and treat them until I'm ready to let them try out the grass?  I have a small tractor to let the chicks be for short periods during the warm days.  But the label on the sulfa-nox says not to treat continually... to treat for 2-3 days, then skip 3 days, then give 2 more days. 
Please help!
