Hello. I am new to this site. I was hoping someone (or many someones) out there could help me with this question. We live on the edge of a large field. The farm uses Round-Up in the spring on his corn and soybeans. The chicken coop can only be built in certain areas (this is a rental) and all of the available spots are less than 20 feet from this field. Will Round-Up harm chicks or chickens? If so, how do I protect my birds when he sprays? Thank you so much for your replies!
