The lowest I've bred a female is 1300g. She is an '07 and she gave me 5 beautiful eggs this season. I have a female who is an '08 and about 950g and eating like a champ. I plan on breeding her this season if she reaches 1400-1500g.

I'd just keep feeding her well and you might be able to start breeding her in the Spring and she'll just lay in the summer.
