It all depends on your location, and so far from my own experience and hearing from others...its hard to make an actual "profit". You can reduce the feed bills a respectable amount...possibly. I sell my eggs to co-workers, some people who the word spread to, and family members usually have some kind of donation; for $2.00. The idea that "farm eggs are better than store eggs and therefore should cost a little more", just hasn't caught on here yet. (but I can get eggs at the grocery store for 99 cents!
, is one I get a lot) Usually, once people start getting eggs, word catches on and more people will start asking.
Depending on your state, you could possibly sell to the grocery stores or restaurants. You will have to look into your state's laws on that topic. North Dakota for example has mostly jump through hoop laws and require you to get a license, but there are states that are much more cooperative.
If you are going to sell hens, you would be better off selling them when they just start laying or about to lay. There again, it all depends on your location as to how much you can sell them for. Seems like more people are looking to take on birds in the spring then in the fall, when they want to lighten the load. Something to keep in mind.
My advice would be to watch your local ads, classifieds, craigslist, bulletin board at
TSC, etc. See what other people in your area are offering or looking for.
