Thats is all opinion as the 1400 gram girl that gave me 6 eggs was 5 years old and just peaked at her size. Her clutch was 590grams for the 6 eggs which is very good. Has nothing to do with investment/money.
I dont see a 1400gram female more at risk than a 1500 gram femae, whats 100 grams 3 meals, its completely safe. And i dont breed females back to back, they get the next season off to recoup.
