I am afraid my Five week old sex link has coccidiosis. I got her about three weeks ago, she has been fed medicated starter feed, and has been outside once. I have her and four other chicks, that are the same age, different breeds, in a brooder in the house. I called all the local pet supply stores and asked about Corid, but none carry it. The only store in a thirty mile radius is closed on the weekends. So, I have questions. 1) Should I separate her from the other chicks? Today was the first day I noticed any blood at all, and there was two spots of it. If I separate her,will she be okay by herself in a smaller box? 2) Since getting Corid is going to be either a day trip, or ordering it online, how pertinent is it that she gets it immediately? Should I spring for next day shipping, or take a half day off work and go tomorrow? Or will a Monday arrival suffice? Thank you all in advance for your advice.
