OK, this may be a common sense question, but I have been known to be lacking in that area frequently. Can I use a spring weed and feed on my lawn if the chickens have access to it? Will they eat it? Right now I cannot keep the few out that can fly over the 5' fence I have. Bonus Question: How effective are the chickens at removing dandelions from the lawn (or do I need to pull them out and then feed them)??
