I need an answer on this question ASAP, as I have alfalfa on a trailer that my neighbor gave me but I see it is dusty! is it going to make my chickens sick if I spread it around in the quonset so they can pick & scratch thru it this winter?? I only have a few hens and a roo but certainly don't want them to get sick. Any replies will be greatly appreciated & ty in advance. I LOVE this site & also my BYC calendar & bumper stickers that came today!!
