They are both from 2007. The pastel is roughly 1200g and the normal is 1600g.
The breeder who sold them to me told me his breeding process is to start cool down through november. Then after he warms back up, he feeds them good for the next 4 months, once they have regained the weight from the previous season, then he starts pairing. So I would guess that he typically would start them in March.
His process seemed quite different from what most people do, as from everything I have seen, you get them to start regaining the lost weight pretty much right after they lay, but it would seem he feeds them to maintain that weight until the next season, and starts heavy feeding 4 months before pairing. So I am not quite sure what the deal is or will be with these two.
