I observed the first lock on 12/19/09 between my Pewter & my Pastel. Since then they have locked at least once every 2 weeks (3 times at least). I've seen her laying cool and know that she is building. My question is, should I start introducing the male more frequently than once every 2 weeks now that she is at this stage.? She is the only female he's breeding, so I'm not worried about maxing him out for other girls. Any input is greatly appreciated.
