Breeding contracts are very detailed, to include the cost of replacing the loaned animal should it die during the breeding loan, figuring out who pays vet bills, how the hatchlings are split, etc.

It's not a matter of "studding out" a male, as the loaned animal needs to be quarantined for a period of time before it's ever introduced to the females. Not many people are willing to let their males be gone for that long.

On the flip side, if the females go to the breeder, they also have to be QT'd, stay at the breeder's facility until after she lays her eggs, etc.

While in theory it sounds like a great idea, there's a lot more logistics that goes into breeding loans and you'll find when you talk to many of the breeders, most are not fans of breeding loans. You really have to trust the person you're entering the contract with to expose your animals to theirs, not to mention the complexities of interpersonal relationships.

Now, where's the "rain on parade" smiley?
