I can use this past season as an example. I have a normal imported female I picked up last year. She was bred and laid on 4/17/11 and laid 4 fertile eggs and 1 slug. She ate 2 days after laying and gained some good weight so I paired her up again this past season.
She laid 6 fertile eggs on 4/11/12 and they all just hatched out perfectly healthy. She is doing great and ate 3 days after laying.
I am not in this for just money, but do understand that this is far from a free hobby. So I can understand peoples desire to make some cash, but definitely wouldn't agree with forcing action for the sole purpose of making quick cash.
Also an interesting note, the female of mine I was talking about locked up within 10 minutes of first introduction, so I think she wanted to go lol
