I have a petite 06 cinny that went for me last season. She never weighed more than 1400gms. She gave me 5 eggs and weighed just over 900gms afterwards.

Some girls are just smaller. If she starts bowl wrapping and starts to develop follicles, I would put a boy in with her. She would mate in the wild at her current size so why not?

I would feed her every 5 days or so and let her fill out. Good luck!!
