My 1 year old Standard Brahmas have started with this. Lost one hen before I could treat her, now her Roo and the 3 in the next pen have started. I have strated treament with Sulmet and Electrolite water and added sugar to keep their energy up. I may have caught it in time but the BIG queston is do I also treat my Chick? they are 9 weeks old (the Brahma) and 4 week old Turkeys? they are on medicated feed still, I was going to switch to broiler feed today, but decided not to considering the illnesses of the older ones. Anyone?
