I think I'd wait? I secretly probably believe they wouldn't make eggs if they weren't ready, just because two of my 2008 females keep locking me out of the black pastel pied project by stubbornly not laying year after year.... but if you wait, you'll have a HUGE female. She'll give you more eggs if you wait a year, and she'll always BE huge, and will probably give you larger clutches down the road.
