My chickens are sneezing

[Beans Eggs]

I have 5 eight week old silkies who I've noticed are sneezing, nothing else seems to be wrong with them. No eye or nasal discharge, and they seem to be pooping fine. They just sneeze, could anything be wrong with them?

They maybe getting a cold. Every so often and especially during the winter, I take my birds, wet a Q-Tip with saline and swab their nostrils. If there is still crude in there, I'll flush it with saline. Then I'll take some Vet-RX (Vicks Vapo-Rub for chickens), cut it in half with h2o, and rub that on their beak, wattles, earlobes, and comb 2-3x/week.

Chickens do not get 'colds'. They can get contagious respiratory diseases that look like 'colds' to humans - these can be treated but the birds will remain carriers and the disease will pop up again when the birds are under stress.

However, chickens can also sneeze from environmental factors - dusty litter, dusty feed, etc. What kind of bedding are they on?

Pine shavings but I replace them and sweep out the coop every 2-3 days.
