This is the first year we have tried to incubate anything. We've got the right temperature and humidity- using independent gauges not the ones on the incubator. Have been turning them like we're suppose to. We put a round of 12 duck eggs in last month and they all suffered early death. Around 2 weeks in. We cleaned it out and tried again. Only 6 eggs this time. We had 1 not fertile, 1 blood ring and 1 quit at about 2 weeks in again. The remaining 3 all had movement and good growth 2 days ago. They are suppose to go on lock down today but when I checked them again it looks like they have died. There is no movement and instead of looking like a blob they look like larger version of the 2 week losses we had. What the heck is going on? Also 2 of them appear to have something dripping inside. Not coming out but when I candled them there appeared to be something dripping like a lava lamp. The other very obviously has a ruptured air sac. These eggs came from out ducks and were not shipped. What are we doing wrong? We currently have a dozen chicken eggs in a separate incubator. All have movement as of right now but they are due to go on lock down in a couple of days and I am worried we are doing something really wrong and we'll lose them too.
