Sorry for your loss. It sucks losing the babies after putting so much work into them! Corid is a brand name and contains amprolium. It's possible they may have the drug you need but under the name amprolium or another company using a name other than Corid.I wish I had known all of this sooner. Sadly we discovered a few of our Cornish cross chicks dead this morning and then saw a few more of them pooping blood. Its Sunday and the one store that was open didn't have the corid (sp?). All we could do was get medicated feed in hopes of saving the chicks that may not of caught cocci yet. We watched one die as we cleaned the brooder area of the hen house. What a terrible death. We have lost eight babies today. Very sad
