Breeders who campaign their mares in sport and breed via Embryo Transfer, how do you or would you structure the sale of embryos or foals? Do you charge a fee to recover an embryo and purchaser covers costs? Do you oversee the ET process and sell the foal in utero or sell the recipient mare safely in foal or do you sell once foal in on the ground? At all stages of the process there are costs and risk to consider. Just wondering how fellow breeders have dealt with this.
