Hello everyone. I am looking for some help with my baby chicks. We got them the first week in June making them about 3 weeks. Its a small group of 12. Last week they started getting sick. The symptoms are: droopy wings, unsteady on their feet, lots of stretching of their wings and every now again they open their mouths very wide like they are chocking. They do continue to eat and drink but they look like they are in pain. One has died already and 7 more are afflicted. I've looked up different diseases and found nothing helpful. Does anyone have any ideas?
