I've done some research, and it's worth noting that pretty much everything called Asplenium nidus is actually Asplenium australasicum. So I should really say it's probably A. australasicum. The difference is based on the sori. They appear as brown, fuzzy, diagonal lines under the fronds. (Your plant may not have sori.) According to the source below, the sori in A. australasicum are half or more the distance between midrib and margin. So basically, I'm thinking it's Asplenium australasicum rather than A. nidus var. plicatum. I've seen larger plants get wavy over time. The source below says the plicatum should be more convoluted.

when did yours start blooming? do they have the separate male and female flowers. mine just started blooming

Sorry i thought you were being sarky.. I hope they are easter eggs bexause theyve been left

Not 100% sure about birds moving eggs but, I would think, highly unlikely. More plausible is they were on some critters menu.
