how long do they poo blood when being treated for cocci?

[srfjeld]

I just got 2 new girls (5 wks) on Monday. By Wed I noticed bloody poo. I am treating them both at the same time, wasn't sure which one had it. They both seem in perfect health otherwise. Today is the day I cut back their Sulmet dose. I noticed a bit of bloody poo again. I really need to get started integrating them with the other girls... my plan is to put them in the run in their dog kennel. But, I don't want to put them out there while they are still having bloody poos.
