Jake,
I just wanted to say that I have an 11 year old female that has laid eggs for the last three years. She typically weighs about 1850 to 200 grams. Every year, after laying eggs, she stops eating once she has got back to 2000 grams. I guess that is her happy weight. Also, her eggs average about 140 grams, and she has had 6 eggs every year. Just my experience with a girl that is average size adult even at an older age.
