I came up with the 100 number on the assumption that’s all a person would be doing. I’ll agree that if one gets into poultry, you don’t need any cows at all. Lots of people around here do the poultry thing. You only need a minimum of 10 acres for it, a $30,000 well and about a million dollars worth of buildings and equipment. However, the integrator (buyer) will guarantee your loan for the buildings and equipment, provide the feed and give you a check for each flock less the cost of the mortgage and the feed. Normally, if you’re a good operator, you’ll make about $35,000/year for the first five to seven years. After that, you refinance your mortgage and make VERY good money. You will generate a lot of chicken manure and what they call “cake” which is manure saturated wood chips. Farmers and ranchers will buy that from you, which is good because you have to clean out and disinfect the houses after each flock to prevent disease. Turkeys work about the same way. You do need a tractor and a front-end loader.
Back to the 100 number. I started to detail how you could maybe make about $35,000/year with that number if you are in the right place (a long story by itself) and own both your land and your cows. But it grew too big for this post, so I deleted all of that. If you don’t own your own cows and are not in the right area, it will take you seven years to break even no matter how many or how few you have, if they’re good stock. A lot of poultry folks around here do both poultry and beef, and use the proceeds of the beef operation to pay off the “rest of the land” mortgage. There is usually some amount of “inter-generational help” with all of that.
Of course, if you don’t care whether you make a living wage or not, or have supplemental income or have some specialty and people nearby who will buy it for a lot more than they can buy it for in the store, it’s different. Some people make that work. But I think you would have to be selling to city folk. Around here, for instance, so many people raise egg-laying chickens they often give them away during peak laying times. And those are “organic” eggs. Just outside a wealthy suburb might be quite different. Probably is.
