I produce between 100+ to 200 animals a year and I am sold out every year now because I am sold out every year does not mean everyone is or will be, if you want to be successful it's like any other business you MUST have a plan, you MUST know YOUR market etc
Shows are hit and miss, most of the time they are miss, you can go to a show and sell nothing again you need to know YOUR market what sells and where it sells if it does.
