The reason that large scale farming is what we have across most of America is two fold, that is about the only way you can make enough money, and it keeps a consistent supply of food for Americans.
Selling eggs I don't think you will get more than feed bills. Meat birds, sell well, but you have to probably do the butchering as most people won't want to do that, and then you will have a lot of regulations. And that is not going to be done on a 2 hour plan.
I think selling point of lay birds, or hatching eggs, or baby chicks might be your best bet. But really, I think that would be very iffy too. It would take some aggressive selling on your part.
To be honest, I think it would be rather easy to loose the 10 grand.
