Hey, you're welcome. I'm really crossing my fingers here for your little buddies.
Out of interest, what kind of bator do you use for your ducks and what humidities do you find to work best for them? I know most folk say 45-50% then up above 65% for lockdown, but I'm nearing the end of my first ever duck incubation and I've actually been running the incubator dry to get the correct moisture loss. I ran it at the recommended humidity for the first 10 days or so then realised they weren't losing nearly enough moisture. So it's been sitting just under 30% since I removed the water bowls and I'll still be struggling to get them to the right weight by Friday, which is when they will go into lockdown. I started off with 18 eggs but a disastrous incubator malfunction combined with a dodgy thermometer took them all up past 104F for probably half a day or so. I was really surprised any survived, but these 8 continued to show development. At the moment I think 6 are good and 2 are probable late quitters. The reason I think that is because while the first 6 are losing weight uniformly and as expected, the other 2 are still losing weight much more slowly, which kind of suggests that they have probably stopped developing any further. Weighing eggs is useful for figuring out that as well!
Anyway, I guess in a few days time I'll find out if my theories about humidity work as well with ducks as they do with chickens!
