Hello, I'm new to this forum and site. We recently purchased 2 pair of show quality call ducks(Charlie Hodum) at the National Chicken Show in Columbus Ohio a few weeks ago. After talking to a number of people and a good friend, Tim Johnson (been in the chicken business for many years) recommended a GQF 1502 or 1550 Sportsman incubator. Where would you recommend buying a good used or new at? I've been looking on craigslist and ebay. I know cleanliness on used is a big issue. Any feedback would be great, thanks for your time.
