death of embryos at internal pipping stage

[shirley rosenbaum]

Hi I am trying to hatch Pekin ducks but am having a problem. The eggs are in the hatcher when they are ready to pip but they seem to be piping at the opposite end to the air sac, and dieThey get to the internal piping stage but seem to be breached Does anyone have any advise

Possibly the humidity was too high. Did the air cells get bigger?

Without some good post mortem pics the best you'll get is nothing more than conjecture.

Yes the air cells got bigger Humidity in incubator was set at 50 and in hatcher pushed up tp 75 Should I drop it to 40? in incubator

Very sorry for you losses.

Some questions for you...
Have any of the eggs hatched normally?
What incubator?
How many times a day are the eggs turned?
Incubated on sides or stood up?
Did you use extra temp/humidity meters? If so, we're they calibrated?

yes temp was 37.2 c

I think 37.2 c (98.96 f) is a little low, probably better to raise to 37.5 c (99.5 f)

@Texas Kiki has hatched Pekins maybe she can help too?

Can you get a few pictures with the light shining in the air cell?

Here are two articles @sumi:

• https://www.backyardchickens.com/articles/diagnosing-hatch-failures-it-starts-with-the-egg.67016/

They are for chickens, but much of the same is probably true for ducks
