I live in the city and don't have any grass in our small back yard. However I think it would be nice to bring my pigs outside to enjoy some good wether together. I don't trust going to a park because of other animals ,and I'm not sure about whats on the grass . So I had the idea of getting a hard plastic kiddie swimming pool filling it with potting soil and growing some grass ( I would also have a pen inside the pool so they won't fall off the edge of the pool and I will always be present if they are outside). Has anyone ever done this before? Or if anyone has any thoughts on what type of grass to plant? Or anyone who has any thoughts on this idea I would love to hear them. Thanks a bunch.
