Not Emergency - But Why are my Chickens Sneezing?

[schnebbles]

Earlier in the summer I got a couple silkies, had sneezing issues but got them cleared up. It's been a while since they have quit sneezing.

Now, my chickens (I think all of them, not just the silkies) are sneezing. Any clue why? I am concerned about this once it gets cold out. It hasn't even been cold at night when they just started sneezing.

Nothing has changed. Started them on duramycin today. (should this turn nasty brown during the day?). It did last time too, it looks gross. I change it daily as per instructions.

I have 3 d'uccles, 3 silkies and a bantam cochin.

Thanks
Kathy
