I am having a very difficult time figuring out what is happening to my poor baby chicks. We have lost 4 so far, all different breeds, but from the same store. We were told that the store did not give antibiotics to the chicks before they gave them to us. The chicks follow a pattern every time they pass. It starts with them sitting with their head and wings lowered and they have no recognition of the other chicks around them, even when they step on or peck them, next they start acting like they are yawning, they then stop eating and drinking, they start acting like they are gasping for air almost, then either have a seizure, or just pass away over night. It is heartbreaking to watch this continue to happen and I do not want it to continue if at all possible. I have started putting Apple Cider Vinegar in their water and a drop of Oregano Essential Oil. I am just at a loss as to what may be going on. If it is a contagious disease then I want to treat my other chicks before they die as well. If anyone has any ideas on what this may be, please help!
