Hi! It has been so long since I have posted anything on BYC. Well the chicken math finally hit me a couple of weeks ago. I have a friend who I got 7 young chickens from ranging from 3weeks to 3 months. I had to treat them for 7days with duramycin due to sneezing and wheezing in a couple. Then I noticed blood in several of their poop. So I ran and got the Corid and started it yesterday. Thanks so much to all who have posted info regarding this stuff. My friend is giving her flock Sulmet instead because that is what her vet told her to do. The vet also told her she could mix the vitamins in with it & she told me to mix with the corid. I have been searching all these threads for hours & have read differen't opinions. I know that I read on here before the reason why you cant do that but I can't find the thread. UGH can someone please help me with this? Thanks so much
