For a while, my hen's been breathing pretty noisily, nothing else seems to be wrong with her (eats drinks and acts fine) so I was curious to know why she's doing that?
Welcome to BYC. Videos need to be uploaded to YouTube or a a similar site, mated public with a link posted here. How old is the hen? Is she breathing with her beak open? Is there any coughing or sneezing, bubbles in one eye, swelling of the eyelid, or nasal drainage?
