I do a 50/50 split. I payall the setup, implanting, calving and management. Supplier supplies the eggs. The number one thing is DO NOT enter into a partnership unless you can completly trust your partner. If you can agree on ALL the marketing of the calves, as they come and in stride, it can be a wonderful thing. I have been into both extremes, and have raised some for a set price. I have a couple of great partners now, when everyone is making money is the best way to get along, and learn from your mistakes. Communication is the key.
