I have heard my chickens sneeze every once in awhile - maybe once or twice every half hour. I'm wondering if I should be concerned or not. How much sneezing is too much? They have no other symptoms that I can see other than my Buff Orpington's crop wasn't full like it normally feels, although I've seen her eating and she went crazy for the BOSS i threw out, like usual. It was probably too early in the day for it to fill up yet. I just don't know if I should treat them for something or if I'm just being paranoid. My other Buff Orpington died a few months ago and I have no idea why. The only thing I noticed with her was that the eggs she laid had a tiny bit of wrinkling on one of the ends and I never thought anything of it until she died. I don't know if that had anything to do with it or not.
