I bought this incubator from Craigslist the day my hen died suddenly. I had no experience with chickens and chicks and didn't even know who to turn to for help. I paid $40.00 for a used one since that was all the was available, but would have gladly paid full price. Every time I candled, the conditions where clear and when I calculated weight-loss, it was at Ideal every time! I recommend this incubator to anyone and everyone! This would be perfect for a school classroom and for all chicken enthusiasts! My Speedy's eggs hatched today with no real problems, she would have been very proud of me!
