Pay for your land in full (100%) and make sure to acquire the land patent to the land you have just purchased, IE get the full assignment to the Land with a true Title to the Land (a Certified Abstract not simply the alleged assurance of Title Insurance); also, make sure the Land and its appurtenances are free and clear of all encumbrances before closing.

I suggest having a legal/law dictionary on hand. Also remember to read the "Definitions" section(s) in each title/chapter/etc of any statutory code. This can help a lot in understanding what a certain code/statute means. Learning the law is the best way to figure out the system and beat it, and I think with some diligent study, you'd be surprised what you find out 

If we are going for small-caliber & versatility, I think the Springfield M6 Scout is the gun you want. It's only a single shot firearm, but it has duel barrels chambered for both .22lr & .410 (shotgun/pellets). It's light and breaks apart in the middle for easy carry. Also in the butt there is a little flip-up section that holds extra ammo for both type of caliber.

Here's a picture:

Yes, according to the statute you cited, when you "slaughter" your poultry, you may not have any "employees" around. Of course because of the wording, there are ways around that if you wish to play those kind of games 

However, California is following Federal Law as allowed by U.S.C. TITLE 21; CHAPTER 10; § 454.

§ 455 & § 456 of the same Title & Chapter discuss inspection. § 458 of the same above discuss Prohibited Acts. § 464 of the same above discusses Exemptions.

Remember Federal Statutes can't be superseded by State Statues, but they can be made stronger, which is what I think you will find in U.S.C. Title 21; Chapter 10; § 464; Subsection C; Paragraph 1; Clauses C & D. Basically, they allow for the packaging of self-slaughtered poultry for resale under certain condition. It looks like the California Statute simply ADDS another condition, which is allowed under § 454 of the above Title & Chapter.

This is all a preliminary/rough draft piece of advice. I highly advise looking all of this up yourself to make fully sure what the law(s) are if you are interested in Federal Aspect of this. Perhaps the rule about not having employees stems from the Federal Food, Drug, and Cosmetic Act. Only one way to find out
