I could show you some recipes that are pretty easy to make, and you can save some money by camping just outside of town from time to time. The money you save on the room could go towards food without making a big dent. As far as the eggs go, if you know a few breeders then they're usually willing to discount prices for you if you're friends.

But definitely try putting aside at least one pay check where you can. One a month is usually a good place to start. It didn't take me very long to earn enough to buy a house. If you don't mind doing your own chores then renting is actually a big money-saver, if you don't travel a lot.
