I have 5 1/2 week old chickens, and thought since it is 80 degrees and sunny today, I'd bring them outside for the first time just for fun. I had a large wire dog crate set up so it had part sun and part shade. I carefully carried each one out to the crate from their brooder one by one. I had 9 out of 11 out there, and suddenly noticed a sneeze. Then another, and another! Within 5 minutes of being outside, they were all sneezing!!! Never before had I noticed any of my chicks sneezing. I am so worried now. It was like all of a sudden... is it my fault for bringing them outside (I had read that it was okay), but it seems a little sudden to be sick in 5 minutes. There are no other symptoms that I have noticed. This just happened within the last half hour, so I will have to continue to watch for other symptoms. What is going on? What should I do???? Should I be as worried as I am? Any help or words of wisdom would be greatly appreciated.
