I purchased some weed n feed this spring and never got around to using it. I wondered if it was safe for chickens and knew i could come here to get info. I found this thread which made me go to the website to see what it says about the safety of the product. I would have never wasted the money had i read the "cautions" on the bag! Here is a link to scott's weed n feed. Scroll down and read then cringe at the thought of ever using such a cautioned product. Yikes
