First goose egg - fertile ?

[Bolfreak]

I have a Pilgrim pair that is 9 months old. My goose laid this egg Feb 10, another the 14th and one today. I’m excited, but want to make sure they’re fertile since I’ve only seen my drake mate the goose, not the gander
This is the first egg - fertile? If yes, I won’t crack any more and let her sit. TIA

Looks like it! It has a distinct bullseye.

Fertile. Gander is doing his job.

OMG I’m thrilled!!! Thanks yall! They have a kiddie pool and also a livestock trough only the geese can climb in and out of. I’ve only observed my drake mating her and very oddly enough, my gelding grabbed the back of her neck and lifted her a little? She was completely consensual
Gander has been hormonal for sure, he goes around trying to intimidate everything with a pulse

Yup, my gander does the same... lately he's been going after me

Congrats on the fertile eggs!! Send some pictures once the little ones hatch!

Here’s two other eggs I cracked, leaving 4 in the nest…fertilized? It’s so hard to see clearly. I took these because one seemed dirtier than the others and one was long and pointy. (Ignore the duck yolk on the left, it’s not fertile and what happens when I cook with eggs They’re a couple days old each:

Finally, today, I observed goose hanky panky. It happened in the horse trough even though there was a random duck that somehow got in as well
Do the geese get “better” at mating as they get older? This is my pair’s first time at everything, they will be a year old in May.
