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 as the others and when she sits she usually puts one leg out to the side and sometimes leans a bit. She seems to have a faster respiration - no panting though. I have checked her out and watched her and she is eating, drinking and seems to have a good range of motion in both legs and no perceptible soreness. My question is two part: First, should I switch to medicated feed? (Though we got 6 different breeds, they are all for eggs.) Second, should I be worried about my little BR or just give her time. I am a horse person with NO chicken experience, but she just seems off to me. A more rapid respiration always makes me worry with my horses, but I realize we are at opposite ends of the animal kingdom here.
