I have one 8 week old that I am treating for coccidia (bloody poop). The others are healthy, and I think this one is on the rebound (has never acted sick, I don't see any more bloody poo). I would like to add in my 5 week olds with them. They are now all eating medicated chick starter. Do you think this is a bad idea? If so, how long would you wait? I've been treating the one pullet for 5 days.
