Hen keeps sneezing help!!

My hen keeps sneezing and not eating very much- I have started to use new bedding could my hen be allergic to this or not?

No way to know without you telling us what bedding you changed to and from.

Tell us about the ventilation also.
Respiratory issues always show up in this forum this time of year when people close up their coops because they think the chickens will be cold.
