Okay, From the information that I've gathered on this site, I think that I'm doing everything that I can up to this point. My girls are 25 days old and I think that I have at least one that is sick. I have seen her sneeze twice now in the last 3 days, I've noticed a little "mouth breathing" but no panting, raspy noises, or other breathing difficulties. I think that her chirp may be hoarse though. She is eating and drinking good but this morning I see a tiny bit of crust in her left eye and nostril. I'm housing them inside my house in the laundry room. When I picked her up to move her to another room ( I didn't isolate her till today) she seemed to be "warmer on her underside than the others that I've held. Nobody else seems ill, but I do see a couple of them doing the "mouth breathing" thing before they fall asleep. Today is the first day that I have isolated the main sick girl, because she has been acting totally normal and active....now that I see the crusties I feel so stupid. Did I infect everyone? What does she have? (Oh I forgot to say that everyone has normal poo.) On instruction from folks here yesterday, I removed all the heat except for the 60 watt bulb (some people thought that they were just too hot with the red heat lamp), I gave everyone a bit of yogurt, added some apple cider vinegar to all the water, continued the electrolyte/vitamin mix and watched everything closely. I feed them non-med feed because they were immunized for Cocci and Mareks at the hatchery. (Does that mean that they won't get Coccidoisis now?) IS NOW THE TIME TO START THE TERAMYACIN AND 4 IN ONE NASAL SPRAYS? SHOULD I SEPARATE EVERYONE THAT I SEE ANY SYMPTOMS IN OR DO I JUST TREAT EVERBODY AT THIS POINT? I need some advice!
