Goslings hatching: Abnormal external pip positions?

[SilkieStruck]

Here are my two Sebastopol eggs, fairly marked up as you can see in the lead-up to internal pipping as I tracked air cell drawdown. Both internally pipped about 30 hrs ago (a couple hours apart, confirmed by candling and noting beak in air cell/hearing peeps and breathing noises) at day 27.5

Approximately 8 and 10 hrs ago, they externally pipped and have been in the hatcher with 75-80% humidity since. I did remove an approx 3 mm piece of the external membrane associated with each pip, prior to placing in the hatcher, as it was very tough. I am not worried about the time frame from external pip to zipping at this point (thanks to all the great resources on BYC) but wondered if these pip sites, especially the one on the right, indicate malposition. I can see the beak on the left egg but am not sure what I'm seeing in the right, and didn't want to open up the pip spot or handle the egg further at this point to try and see what position he's in since it is early and both goslings vocalize and move the eggs when I shine a light in to check on them.

As I look at the right egg I can't imagine the chick being in the proper position. I stopped marking the air cells at internal pip, so the markings don't quite indicate the air cell boundaries; but both external pips are within the air cells.

These were shipped eggs with fairly large saddle air cells noted prior to setting. They were incubated with the wide end slightly elevated, manual turning every 4 hrs (except during night) and were weighed/tracked throughout incubation with desired weight loss 15% achieved prior to internal pip. They were dry incubated at ~25% RH, temperature 37.5.

Any thoughts on whether these pip spots indicate trouble?

I am so grateful for this site-- I would have been completely blind without it!

Thank you for your time!

Following up on how the hatch went with these eggs. The one on the left proceeded to zip and hatch almost unassisted (after he zipped and continued to struggle against the progressively tougher membrane without progress, I did tear the membrane after ascertaining complete yolk sac absorption and recession of vessels, after which he promptly did the "jack in the box maneuver" and was out). The one on the right zipped about a quarter of the way around the shell then stopped making progress and gradually came back to almost the starting spot. I did a slow progressive assist with her and her position was basically tilted so that the right side of the body/neck/wing was against the membrane separating chick side and air cell side; rather than being sort of perpendicular to it, if that makes sense? By the time I got the top removed from her shell (again all in a slow incremental progression), yolk sac had absorbed and vessels receded and I did help her get her head/neck free, put her back and she did the rest.

Ended up with two lovely babies and they are doing great! Below, Princess Bubblegum (left) and Finn (right) enjoy some snuggle time with my son




I am so, so grateful for Pete55's incubation and hatching resources, which I read and re-read many times over the last month (as I get older, it just never sticks the first time!). I would have been lost without that information. I couldn't begin to say how many frequenters of especially the goose threads have positively affected this experience for me, and I am certain directly affected my success-- I don't know if you all can appreciate how much people learn from your daily exchanges with each other!


Okay just one more picture, because he's so handsome.....
