Oh my. There's a section of BYC called BSA - Buy, Sell, Auction. It's internal to BYC ... sections for hatching eggs, for chicks, for older chickens, for Other Poultry, for Everything Else (like chicken diapers, shawls, saddles, and egg carton labels, for example).
I have 3 bantam cochin hatchlings 3 days old, 3 blue lavender orpington hatchlings ONE day old, all in the brooder and all from eggs I bought or won at auction on BYC. Plus another 7 eggs in a third incubator, also filled with eggs won or purchased from BYCer. Plus two more sets on the way (now that I have 2 empty incubators).
For the love of god, don't go there. ROFLMBO.
