I have a 3 year old RIR Chicken that is having these soft sneezes / honks intermittently with open mouth breathing shortly after.. She seems to be having more respiratory effort after the sneezes. No ocular or nasal discharge. Comb and wattles are red, walking around fine but seems to have slowed down as if taking a stroll instead of more active then normal. Symptoms have been ongoing for about a week. Not sure if she has gapeworm or something more long lines of a respiratory disease. I did change out old bedding and replaced it with straw and pine shavings to help cut down on the Dust. As far as I can tell still eating and drinking fine. I do have a video of it but the file is too large. I'll see if I can shrink the file. Any help is greatly appreciated. TIA.
