We have several 12-13 wk old RIR chicks. We started out with 16 about 3 weeks ago, and seven of them have died over the last two weeks. Now one of them has eye watering & squeezing shut plus weird breathing with beak open and watery reddish orange poop. We have had it separated from the others since we first noticed it, and she is not eating or drinking well. We've been treating her eye with saline eye wash, and trying to get her to eat and drink. Now another in a separate enclosure is starting the same weird breathing with her beak open and sounds like she is sneezing or wheezing. Her eye looks fine so far, but we don't know if it is the same problem as the other. Does anyone know what might be causing either of these problems? Also, should we put the one that just started breathing weird with the other that is separated even though it doesn't have the eye problem? We are desparate for some help and answers or advice. We have lost almost half of our new flock so far and can't afford to lose them all! Don't know if all the same issue or just one of those things with new chicks/pullets.
