We are new to chickens....our oldest chicks are almost 3 months old. We have younger chicks, 3 that are about 6 1/2 weeks old and 9 that are about 4 1/2 weeks old. With our older chicks, we have noticed a sneeze or two here and there...and I have read that that is normal in chickens and not to worry. In the past day, I have noticed some of our younger chicks sneezing and little more noticeably...we have had a lot of pollen here...can this bother chicks? Our chicks don't seem to have any other symptoms...they seem to be eating, drinking, pooping and doing other chick stuff. I have looked at disease charts and other posts....but just wanted to see what other people thought.
