You say above that you ralise now you will have to arrange return of any birds and then claim cost from the breeder. What will you do if the breeder refuses to pay the carriage fee etc?
I would love to run a one loft race, I wouldn't need to do any breeding, keep any stock birds, feed and clean all winter etc. Then in the spring sudenly have a loft full of lovely squeakers to train and race then get rid of them before winter comes again.
If I did i wouldn't want 40% of the sale price, yes something to cover feed etc but that would be all, why, well if they were my own birds i'd be paying for the food, fuel, medication, entry fees etc out of my pocket and fairly sure there would be little or no profit at the end of the season! I would just get great pleasure out of seeing the birds win and perform!
