I used to help my uncle in his greenbean field. All I did for him was help pick, but we worked our butts off. Cash money and it made me happy to be near my childhood home near my relatives, so I gladly did the work, but I don't think he charged enough, because if he'd have given me 5 dollars more/bucket, I wouldn't have been overpaid. If I'd do it again, I think I'd prefer to do it for myself to get a bigger cut, but I'd charge more $. I know how hard I worked that summer. I think of that, everytime I open a can of greenbeans.
I turn a profit on my chicken operation, but I don't just do it for the eggs. If I would, I'd still be waiting to catch up on my expenses. I bought a big, second hand incubator and I do about 4 hatches a year from my own stock of chickens, guineas and geese. I have also hatched out ducks, but they all drakes. I sell the chicks 2 for $5.00 straight run. I'm thinking I will do much better this year because I obtained the right breeds to start a sex-link project, so I can guarantee the sex of those chicks. So I plan on selling my pullets for 3.00 and my cockerals for 1.00, which I know I will be keeping most of the males until slaughter age, but that's part of my plan. Some of my customers want meat. If you don't under sell yourself, you can turn a profit.
You got to use your head and keep down expenses though. I go to the river and get my grains in bulk, so I don't have to buy processed feed at an ag store. There are about 20 or so reasons why I turn a profit though. Don't let anyone kid you.
You have to be knowledgeable about chickens to do this. People come with questions and if you look and talk like you don't know anything, they won't have respect for you.
I also am just getting ahead with my beekeeping. It took a few years before we were set up enough to harvest to sell. Thats a major chore when we doing it. I looked around at prices and the nearest beekeeper undersells his honey. I refuse to do that. I'm not desparate to sell my honey. If I have to sell for less than I feel its worth, I'm keeping every drop. But guess what.......I'm down to only 4 jars and its going to be another 3 months before I harvest again, so DH is going to start us some meade. If you honest and demand a fair price for your work and investment, you will get it, most likely.
My parents have an orange orchard. They made decent money on it, but it was a job. They had to go out of our area to sell where its colder to turn a profit and they had a lot of strange experiences. They got old and sick and gave me the crop. I tried so hard to sell it, but I can't. Its too big and I already had 2 jobs and was homeschooling. Its fine, if its your only job, but I couldn't do it. I would think they could have had less orange trees, and planted a huge garden to satisfy more of our local needs, so we wouldn't have had to leave this area. I tried to strike a deal with a wholesaler, but Mom and Dad caught a fit. Besides the guy never got back with me. Apparently the produce you buy at the store....well the farmer who actually grew it, got very little of what you pay for your produce. It would be good though, if I was retired, with less obligations.
