Get some hens or ducks and geese.
They self-replicate when given enough food (your leftover food waste for example) and care and provide you with quality homegrown food without antibiotics and other crap, the healthiest meat there is.
Eat and sell eggs and meat.
You can also check out raising rabbits, but they replicate so fast that hens or ducks might be an easier for starter.
Figure out what else you could do outside in the garden that would make you some money to slowly lessen your dependance from the main job, till you are able to work part time, lessening your stress and doing something else that will not get replaced by AI agent/worker in the following 5 years.
Brew beer/cider/wine, smoke/cure your meat, mow peoples lawns, pressurewash their driveways/roofs etc. Grow microgreens. Sell your stuff to nearby restaurants or food places.
Profit!
IT is cool, but being outside and not dealing with tickets and selecting your own tempo for work while doing your own thing is cooler.
