They were on the medicated for the first 4 weeks, and once they moved outside into their "big girl" coop, I switched them over to the unmedicated [because I refuse to buy purina and I can't find the big bags of the medicated dumor food]
Should I put them back on the medicated? I have a little bag of it...or is it too late for that?
Corrid might be better Sulmet will work. If you've already given Sulmet don't give Corid too. The medicated feed is supposed to help prevent Coccid and it's recommended to keep them on it at least 8 weeks. Sounds like you took them off the medicated too soon.
