I have 4 easter eggers that I go from a farm supply store. They are 2 weeks old and on a non-medicated, organic chick starter. They have been sneezing for about five days now with no discharge. Yesterday I did notice a little moistness under one chicks nostrils and this morning two of them had it. It is just a tiny bit and they are still sneezing. Is this nothing or a disease? Is there any way to treat them? I have been putting vetrx under their wings and on their nostrils. I am very concerned because I don't want to spread any disease to my adult flock. Any help is much aappreciated!!!
