I've only been to one.. but as I understand it, a swap is a mostly informal gathering where folks bring their poultry (eggs, chicks, young or grown) to sell or trade them. You don't have to have birds to participate, but you will probably need something to transport your new birds home in. I believe they usually happen in feed store parking lots or in farm fields .... and they are FUN.what is this "swap" that you speak of?? We still need to get a coop set up so we're a few weeks off from needing hens but I want to get things rolling.
