I bought 8 BBR and 8 Slate poults this year. They guy i got them from is great. Right off the bat 2 of the slates started acting sluggish and died so I though Coccidia. So I started sulmate every other day. then I moved them to a pen with outside run (they were lots olderlike 6 weeks) and they started dying in droves. so I moved them back into a inside pen and still two more have died. I don't know what else to do. My adult RPs are dong great but I can't raise apoult to save my life. Crystal
