My 3 welsh harlequin duck eggs are on day 31. My temperature was to low till day 18. It was at 99.5 and was advised to raise it to 102 for still air. My humidity was at 55% till day 23 when I realized the air fell was to small. So I ran dry till day 28. The air cell were caught up, put water in an ran ar 65%. The cells dipped down and internally piped on day 29. Day 30 I placed a safty hole because no external pip. Now day 31 I peeled the safty hole of one back to reveal the membrane. Following these instructions

The veins are still full of blood and the duckling looks huge. Are they to swollen from the high humidity early on to progress any more. I'm at a loss as to what to do. I nicked the membrane with a piece of shell and it bleed a drop of blood then stopped and clotted. It's still making the yawning chewing. I assume trying to absorb the yolk. Will it just take a long time to absorb then have space to maneuver out? Should I check the other eggs..

The other two eggs are hardly moving or making much noise

Are the other two eggs also internally pipped? If so I would put in safety holes.

Yes their was safty holes in them. I discovered they were trying to pip in the bottom of the egg because of bruising. So I careful put a hole in the shell on the bruise. Chipped the shell away. Moistened the membrane with coconut oil. And cut it right over the bill. Then chipped the safty hole away and they were not piped in there, so put the oil on the membrane in there as well. Theres still veins and a little yolk sac so just waiting for two to absorb. One hatched already.

Great job! How are the last two doing now?

The one with the smaller hole, absorbed the blood but not the yolk, then died.

Oh no

You did what you could, there was no more you could have done for it.

Thanks. Do you know if there is high mortality in the Welsh harlequin breed? Someone mentioned to me that maybe there is and that's why it's a rare breed? I'm having the hardest time ever getting any to hatch!

No, I breed them and they don't have a high mortality. Lots of things can go wrong in incubation that can cause issues. Your humidity was too high this time around and your temp too low at first, so that probably played a large role in the bad hatch rate. Now that you know that and have those corrected, you should have better luck next time around
