Congrats!! :woot They're adorable.
The "wiggling" usually does indicate that the goslings are preparing for hatch - but it can begin a week prior to hatch. Hatching's hard work. 😁
That is exciting! :ya
Speculatively, it's possible that the temperatures during shipping could have begun the incubation process en route to you...it's also possible that the eggs may have begun incubating before they were shipped. It may be easier to draw conclusions when you have a hatch...
I would stop turning them now and let them continue to get into hatching position.
Remember that even after they pip, they usually take much longer to zip and hatch than chickens do.🐣
If it's a breed that would normally hatch in 28-30 days, it's too early unless temps have been too high during incubation (or count is off, eggs had begun incubation before being placed into incubator, etc). 🙂
Eggs can begin moving days before they actually pip. I typically lock down goose...
