Maybe there is dust that the fan is blowing around?It's a large dog kennel, about 4ft by 2ft, in a wooden shed. I do have a fan near them, but not pointed directly at them. It's actually pointed at me, I sleep by them incase they need something during the night. Here's the place they'll be moved to. I have to use shavings again in the large one because the paper towels would be too expensive. I don't think theres anything in the air that could be irritating them, I try to avoid spraying things in the house. Can you recommend anything else that could help stop the sneezing and mucus?
Try turning if off for a day and see if the sneezing stops.
They should be sleeping at night...they shouldn't need anything.
Hens go broody when you don’t want them to… and won’t go broody when you do.
