Sneezing?

[Pele]

I had a batch of chicks who did this. I think it's the natural result of all the snarfing they do. I'd sneeze too if I vaccuumed up food like they do!

You should see my broilers are feeding time! They quite literally DIVE in the feed, and are forced to come up for breath once in a while, gasping and sneezing as they do so.
