None so far. In 2012, I paired up 9 2010 girls that were 1400g or bigger and none went. This past year, I didn't pair up any 2011 girls. Next season I'm going to try again with some of my 2012 girls that are huge. I've talked to a well known breeder who produces 100+ clutches a year and if I recall correctly, he gets about 20% of his young females that are up to size to go.
