My daughter was given a pekin duck egg by a farmer at the fair. She decided she was going to hatch it and set out to 'incubate' it with a heating pad. I never thought it would start to develop but it did. So I assembled a crude incubator with a Styrofoam cooler bowl of water and a thermometer/humidity gauge. All had been going well until last night when the temp spiked to 109 for up to 6 hours max (I checked it at 11:30p and it was 100, but at 6a it was 109. We candled it the night before the spike and we had good movement, lots of veins, etc... But now after the spike I barely see any movement and there is a spot that looks like maybe pooled blood. We still have veins but I don't know how long those would stay intact after death. Do you think it died? How long would the veins stay? Or is it possible it is at a developmental stage with less movement? We are at day 17. It is still in the incubator back at 100. Thanks for any input.
