I am thinking of putting cows out on a share or lease. What would be fair? Is anybody interested?

30/70% split here the guy doing the work get 70%, and feed. Basically pays everything.

90-10 split of calf check, 3-7 year olds, 10 year old blacks automatic post weaning trip to fall sale barn, char x bred, cattle owner responsible for death/dry loss immediate replacement with like kind animal up to 5% after 5% lessee replaces. Nothing mean, or wild. Not interested but leases are tough to make work today.
