How do swaps work? Do you just show up and trade/buy/sell birds? Does it cost anything to get it? I'd like to know asap, please. I am going to the swap in Eaton, Ohio tomorrow and need to know. Its kind of a last minute thing, but this is the only chance i'll probably get at rehoming my roosters. Plus my parents want to go which means they are moving to the dark side. Muahahahah! Thank you!
