I'd buy my landlady's property, let her live in her house rent free, and go hogwild(er) with my chickens. Hire a professional coop guy to build a REAL, big coop suitable for 50-60 chickens, put all the chickens together.
Have a LONG discussion with the financial planner my sister used (and which I am supposed to use now that she's gone and I inherited her IRA) and do whatever is best with the rest of the money.
I don't have expensive tastes, but I do covet some things. Think I'd not work any more, that's for sure. 10 years ago, I always said I would still work, because I love my job. I still love my job but I am loving chicken keeping more. Only got into chickens in late 2009.
