Thank you all for replying. I sort of feel out of my element here and it is great to be able to bounce things off folks.
Seem to have two different opinions. Are there different kinds of medicated feed? One for Marek's and one for cocci?
We have 7, 1 wk old chicks that I have been feeding Dumor starter feed. I thought it was medicated, but I think I was wrong. The chicks are vaccinated for Mareks, but not coccidiosis. Most seem to be fine and growing FAST, but one I am not so sure about. She (BR) doesn't move around as much...
