if you are interested in farming/raising your own meat, a lot of people will recommend chickens as the first choice. Chickens can be bought for less than $5 and their feed isn't too expensive. Your most expensive initial cost is going to be setting up a coop assuming you don't have a shed or something that can be retrofitted into a coop. Chickens are fairly easy to care for and their feed can be supplemented with food scraps and allowing them foraging time.
But actually, rabbits are even more efficient. But a lot of people are put off by the idea of eating rabbits (which is fair!). Rabbits reproduce regularly, generally create more lbs of meat to feed than chickens, don't require as much space (but should be given as much space as you can give them ofc), and also provide a beautiful and warm pelt if they are dispatched correctly. Rabbit meat is higher in protein but lower in fat compared to chicken as well. I haven't had a chance to try it myself, but I have also been told it is more easily digestible for those with stomach issues (probably because of the lower fat? i know I had issues with digesting animal fats for a while after my gallbladder surgery)
From what I understand from reading books about raising meat rabbits, is that rabbit meat used to be more commonly stocked in grocery stores in America, but PETA/other animal rights groups would frequently protest at these stores until they were basically bullied out of carrying it. I acknowledge that eating rabbits probably isn't for everyone, but imo it is a shame that it isn't more readily available. It feels like how it's treated more like a high mark up luxury meat, when it really shouldn't be.
