Yep, I figured I could wear protective goggles & mask from the powdery dust but I couldn't put goggles/masks on our chickens if they kicked up the dust in the coop or garden. Silly, I know, but I just don't relish dealing w/negative respiratory issues & my DH is super breathing sensitive. He sneezes the minute he walks outdoors. My nephew the same way!I was warned about the breathing issues years ago by two very wise men and was made so aware , that myself and my animals never had one single issue.
