My 2008 female pied was happy to lock with my black pastel all last winter at 1400 grams, but she never ovulated. I don't think that's a pied thing---I think it's a young, smallish female thing. Some girls will produce eggs at 1300 grams and 2 years, but you're just much more likely to get eggs out of either a 1300 gram 3 year-old, or a 1700 gram 2 year-old.
