If your geese are just maturing they might be tending to lay larger eggs, particularly this early in the year when they will be 'hoping' for the chance to hatch them.

I keep a few quails these days but in the past have had chickens, Rhode Island Red and Leghorn, black and white bantams, and geese way back when we had a large orchard.

The quail eggs have a really large yolk for their size - the only trouble with boiling them is getting the shells off. Six or eight of them make a really strange looking fried egg.
