Hey! Thanks in advance 
I have 6 hens currently and tonight while in the coop at night we noticed two of them were wheezing. The wheezing would come and go and I heard one of them sneeze over a span of approx 5 mins. Other than that they seemed completely healthy - they were out free ranging all day and acted completely normal. Other than one of them just started moulting heavily yesterday. I’ve only had chickens for a year and a half, so I’m new to this and am not sure what I should be doing. Any advice?
