Yes and yes. Assuming they keep feeding through the season you shouldnt have any problems getting the females to breeding weight.
You have a good shot with the males too (I have a 325g male breeding for me this year and a have had a 375g male breed for me a few years ago). However, some males need to be bigger before they are interested. Most are breeding by 500g (though my pewter made me wait until he was over 800g).
