hmm, I was wondering the same thing but i didnt think people did it like that. I thought negotiation was the way..ie you can have this and this if i can have this type deal
I would also think that the person providing the female would get first pic. i mean they house the animal, breed the male to her, incubate the eggs...
Yeah but if youre the one asking for the male on breeding loan, it makes sense that you give up first pick. That means someone is sending you an animal, and that requires a lot of trust.
