She is an 9 yo Buff Orpington and has been sneezing for about 1 and 1/2 months.She started about the time my rooster died and I introduced some new pullets.I have considered that it might have been a disease that she got from these other chickens but my rooster seemed to have had a stroke and all my other hens are fine.She shakes her head when she sneezes and her comb is oddly colored.Please help!!
Welcome To BYC
Can you post photos of your hen and her comb?
How often does she sneeze?
Do you notice mucous, facial swelling, bubbles in the eyes or other respiratory symptoms?
Is her crop emptying overnight?
When was her last egg, does she have any bloat or feeling of fluid in the abdomen?
She may have picked up something from the newbies, hard to know. If this has been going on for a 1 1/2 months and she's eating/drinking/relatively active, it may be a virus that has to run its course.
