We live in the desert, so dust is a given here. Plus, it has been very windy lately...up to 70 mph gusts. But, the brooder room is not the typical dust we see elsewhere in the house! The wood chips are "dust-free", which I think is bologne. The room has fine dust EVERYWHERE! It even makes one of my chicks sneeze (and me!)! The dust is a very fine, whitish gray and is caked on EVERYTHING! The chicks are only 3 weeks old and the room looks like it hasn't been dusted in years! What is causing it? The not-so-dust-free "dust-free" litter? Hoe do ya'll deal with it without irritating the chicks respiratory systems?
