I know this may sound odd, but I have had the honor of owning a 3 legged duck for the past 4 years. That's her in the pic below during her Ripley's Believe It Or Not photo shoot. We made it into their Dare To Look book last year. Her parents were supposedly full-blooded Pekin, but she looks just like a Swedish Blue. (maybe a Swedish blue drake flew into the lake for a visit). I hatched her in an incubator along with her 2 siblings. A dog killed her the other night and all I have left are 5 eggs that I really hope are fertile and will hatch. Her hatch rate has been rather low I believe due to her odd anatomy, but these are the last chance to have her prodigy. I had one of her babies she hatched out last fall, but he was killed in the attack as well. The oldest egg is about 7 days old so I know time is of the essence. I have a still air, Styrofoam incubator that has served me well, but the little cheap thermometers from the feed stores I'm afraid are just not accurate enough. It seems almost impossible to get the temp where I need it because I can barely read the variances. I put 2 in there today and one read 92 and the other 99.5. So I need to know, what type of thermometer do y'all recommend to be the most accurate. I'm tempted to put a whole bunch of them in there, but I'm afraid of many different readings and not knowing which one to trust. I recently set 2 dozen of her eggs and none of them developed. I was using the thermometer that read 99.5 but if the one that reads 92 is correct, maybe that's why they didn't develop. Not even a blood spot. Would 92 be low enough to where the embryos would not develop at all? Also, would a small fan placed inside the incubator help or should I just use it as a still one? Any help you can give me will be most appreciated.
