Deformed gosling died on pip.

[Impress]

I have eleven Chinese Goose eggs locked down and hatching. The first three were hatched this morning, I peeked in just a few minutes ago to check the other egg with a large pip hole and realized the gosling was dead.

So, eggtopsy naturally. It had an oversized head that was deformed, bulging on one side and kind of smooshed on the other side. What could have caused this? The eggs were bought at a swap, so I don't know the bloodlines, could these eggs be from inbred birds? Would that cause deformities? I am incubating and hatching in a Brinsea OVA 380 and have kept the humidity and temperature spot on and perfect.

im bumping this as I just lost a gosling to the same description, pipped yesterday (due to tart hatching today) no interference good progress until this mornings check gosling deceased, finished cracking egg to find huge yolk unabsorbed, and the goslings head oddly shaped mor like an offset oval, squished on the top on one side, bulging on the top on the other and a fluid filled bulge funning down hat side of the face and neck.

using a brinsea octo with auto turner and haven't had this issue before...
very confused.
have another egg externally pipped ad peeping this morning...and 5 more in there im hopeful for, but realy unsure as to what happened....was this little guy doomed form the start or possibly faults during incubation (we opend misted/cooled 10 mins a day until lockdown)
temp and humidity have ben spot on with both the included thermometer and a digital addition.

such a sad sight firt thing in the morning.
this egg was from our heritage embdens and this is their first year laying.

I have had this same problem In the past. I would love an update if anyone knows what caused this deformed swollen head.

@Iain Utah had a gosling hatch like this. Hopefully she’ll see this tag.
