@Saigey as far as I can tell by the pictures you post your little ones look very healthy. As long as she is acting normal and doesn’t appear in distress I wouldn’t worry I have a goose who is 8 yrs old she hasn’t laid in 4 years. If concerned a vet could do xrays to look at her reproductive trac but just my opinion if she’s healthy and doesn’t lay it’s a blessing having lost a few to egg laying problems it’s heart breaking.
