Can the fertilizer hurt the chickens if they decide to eat some of it? DH decided to toss some grass seed into some bald spots in the backyard lawn. He used the kind that's already mixed with fertilizer to help the grass seed grow. The fertilizer looks like tiny green gravel kind of like what you see in home aquariums. There are no weed-killing chemicals in the seed/fertilizer mix. Just grass seed and fertilizer and some moisture releasing gel particles. He put it down about a week ago, and we watered every day and it rained a heavy rain at least three times since then. But the green "gravel" hasn't dissolved and is still visible. The chickens are two Delaware hens of one year of age each, and a three year old Marans hen. (Not bantams.) Moderator: Not sure if this is the proper forum board for this question. Please reposition it if need be. Thanks.
