Okay, near the beginning of August, one of my chicks, about eight weeks old then, got an odd sickness that started out with only sneezing and a little wheezing. About a month later I found her shivering, just skin and bones, underneath a small box-container. She seemed to gasp for breath, and gurgled, or crackled a lot. After three days of her seeming to get better, she died. Now my entire flock sneezes quite a bit, and the leader, Georgia, has been wheezing a lot. She has a lot of watery discharge from her nostrils, as well as a couple other chickens. Today she is fairly listless. Please, if you know what this is, tell me. I couldn't stand loosing another chicken.
