Need help for mandarin duck hatching, first tried its dead

[Vinnyz]

Hi I need some help please my mandarin duck hatched dead.
I’m using 37.5-38 degree humidity about 63
but they ended up dead I am not sure what went could have went wrong

Is that 63% throughout the entire incubation? That would have been too high. I'd try it lower, perhaps around 30% to start, and monitor the air cells or egg weight loss to pin down where you want it to be.

Mandarins in general are a bit harder to hatch, and then after hatching it can be hard to get them to eat. If they're from a pair you own, I'd recommend just letting the hen try to hatch and raise them.

63 percent humidity for lockdown or for the whole incubation period?

It’s throughrout the whole incubation

So I start around 30% and how to estimate when to increase can you give me an example? Of how to observe? Example of the egg weight lost I should increase more humidity by how many %

To weigh your eggs to track moisture loss, you will first need a base weight. Right before putting your eggs in the incubator, weigh them using a kitchen scale and write it down.

This weight is your base weight. An egg needs to lose 11 to 13 percent of its weight by the time it enters lockdown. Shooting for 12% is what I like to do since it's right in the middle. In that case, the formula for determining how much weight an egg should lose is the egg's weight multiplied by .12. So if an egg for example weighed 100 grams, it should lose 12 grams by lockdown.

If your eggs are not losing the correct amount of weight, you know you need to adjust humidity. If they lose too much weight, that means they are losing too much moisture and your humidity is too low and needs to be raised. If they are losing too little weight, it means they are losing too little moisture and your humidity needs to be lowered.

And at lockdown you increase humidity to about 65%.

Thank you so much will attempt again!

Thank you so much will attempt again!

@Pyxis mat I also check with you if the temperatures are alright? Or need different adjustments as well

Temp is fine if you have a calibrated thermometer to test it and know it is accurate. 63 percent is super high, that definitely would have made them drown when they tried to hatch. I do 35 percent until lockdown and then I up it to 60-65

Ok thank you so much! I googled in chinese and that’s what I got
