I got 7 chicks from TSC in April and one of the red sex links sneezes. She did this a few weeks back, right after I had moved them from a brooder box into a smaller coop so I didn't put a lot of stock in it, thinking it may just be the pine shavings. I have since moved them to an outdoor run and larger 8 by 10 coop and hadn't really noticed anymore sneezing from her until yesterday. I also heard another hen sneeze but only a couple of times. Reading some of threads about sneezing now has me very concerned. I saw a slight clear discharge from the nose of the sex link, but otherwise she seems fine, eating, drinking, flying. Any advice? I've seen some posts about antibiotics,but am new to this. I only have the 7 chickens, and they are all the same approximate age, so do I treat everyone? Perhaps I am jumping the gun...other than the occasional sneezing she's fine but I don't want something progressing.
