I have a few chicks that are gasping and have their wings fluffed up. I think it could be coccidiosis. (no runny noses, sneezing, or coughing) I do not want to give them any antibiotics. Is there something more natural that I can do for them? It is only a few of them and I had already given them ACV. Is this going to work, and how often can I give this to them? (they are about 3 weeks old) Should I give them probiotics? Thanks!
