Sneezing chicken

[Isaac 0]

I have a Salmon Faverolle hen that has been sneezing constantly for about the past week. She doesn't have any discharge from her eyes or nose, and seems to be perfectly healthy. She is the only one of my hens that is sneezing and has not spread it to the others, which makes me think that it may not be a big deal. Her poop looks just fine like the rest. We recently started to use straw instead of pine shavings in the nest boxes... could that be the cause?

We recently introduced a new rooster to the flock, and she has become his favorite hen... would that have anything to do with it?

Sounds like a minor respiratory infection.I would start her on Tylan 50.1/2 cc for 5 days orally.Straw doesn't absorb that much moisture i would switch back to pine shaving.Flocks can be active carries of a respiratory disease without any symptoms it usually shows up when they are stressed.My guess is they are in the coop because its cold? and she is at the bottom of the pecking order causing her to be stressed.Thats just my two cents
