Patience my friend. I waited long time last year for a lock over 2 months and being a newbee was all excited when they finally did, then she never did produce for me. This year so far I've been lucky within 15 min. I had a lock with one female and then within 5 min I had a lock with the other female. But last year was toooootally a different story. I waited and waited and waited until I was about crazy!!!!

They will do it, do it when they are good and ready. You can't make them go, well except the obvious temp changes and such, until they are ready.

Besides like everybody has said, it is still early.
