16. Raise Chickens And Sell Their Eggs

When you think of pets, you tend to immediately think of the classic domesticated animals like dogs and cats, but other classes of animals can be kept as pets too! Chickens, for example!

Raising chickens is a good way to make some extra money, because they cost very little to buy and can produce eggs on a surprisingly regular basis.

Just make sure you keep them in good conditions – such as in a back garden with a coop or pen, as opposed to keeping them horrendously and needlessly cramped.
