My dad wants to put fertilizer the yard. I told him if he did I would have to keep my chickens locked up for about three weeks. What will happen if they eat fertilizer? We had some plants started in a bucket that had mircale grow in it, he did't know there were seeds in it a dumped all of the dirt out. They ate some of it will they be ok? If he does put fertilizer on the yard what should I do with my chickens. We have two acres so that is alot of fertilizer.
