My cockerel sneezes as he crows- problem?

My LF Lavender Araucana Cockerel crows weirdly- he does the cock-a doodle-ACHOO!  He does this about every other crow- I also find him sneezing a lot neturally and his breathing is a bit noisy sometimes.  Other than this, he an amazing boy- got his first offspring in the incubator now!  Is this a problem?  Thank you
