Egg from tiel or conure?

[YUMgrinder]

So we have a bird room, they are all allowed out of their cages during the day to roam around. They often hang out in others cages. Today we found an egg in the conures cage, but they both are dna sexed male. The only dna sexed female is our cockatiel. Can anyone confirm this egg is indeed, a cockatiel egg? Otherwise we have more girls than we thought.

It does look like a Cockatiel egg but I have never seen a Conure egg.
That being said I found that the clutch of eggs my Tiel laid varied in size.

I have never had a tiel, but-- gut instinct was cockatiel-- never seen a conure egg either.
