I keep half a dozen of my own chickens in my backyard...which means about half my daily protein intake comes from eggs (which is a great source, btw). And my chickens free-range in my backyard and largely take care of and feed themselves (supplemented with chicken feed but they get most of their daily intake from the bugs/plants in the yard). I still do eat meat almost daily, but the quantities are a lot less than what I was doing a decade ago, and beef is less than a once-a-week thing for me. Like you, I'm trying to get back in shape and watching macronutrients (like protein) very carefully and trying to hit certain daily minimum numbers.
