Two of our birds have developed these yellow growths in their mouths. There are no other symptoms other than this hen making a little bit of sound when breathing due to the obstructions in her mouth and attached at the back of her tongue - she can still run super fast though since I could barely catch her - she doesn't act sick at all, no runny nose, eating/drinking fine. I was able to remove w/ iodine-swab the pieces on the sides of her mouth in the photo, but the large part at the back of her tongue will not come loose. The rooster in the photo below that just had it near the tip of the beak and none behind the tongue so he's showing no signs of illness at all and everyone is still eating/drinking fine. So, is it wet pox? I just need to find out somehow for sure before we vaccinate the rest of the flock (never have done that before but would do it to save the rest of the flock - we have 50 free-range layers and 50 bantams in breeding pens). I don't see any birds with dry pox this time, though we have had that before (2 yrs ago). We do have mosquitos and flies already due to the wet and mild winter.
