I have a couple thoughts....
Vegetables, fruit, chicken, beef, etc. are way to mainstream. It will be hard to make enough money with all the large farms selling them for outrageously low prices. You need something that sets you apart.
Honey is a nice idea. The start up is a big expensive. It can cost around $150 for bees and $300+ for a hive. But after that, it is relatively free of cost. Nature feeds the bees, and the bees help nature grow in return.
Organic, free range eggs you should give a try. If you get a lot of nice breeds you can have a wide variety of color. Blues, greens, chocolate, and, of course, brown.
Goats milk soap is something people really like. I don't know where you are, but around here, people would go crazy for it. Especially if you inform the customers about it, how you make it, and how it is better for your skin than store bought soap.
Fish farming can be very profitable. If you set up some kind of aquaponics system, you could do well.
