I've made about $30,000 selling lovebirds for $55 each! I used Craigslist and ads on other websites and local newspapers. I bought the birds from breeders and then resold them. The lovebirds breed quickly, so the demand is pretty high. The only problem is that you have to have room for about 50 birds at a time. So you have to have a place to keep them separate from your pets or kids. It's really easy to get started in this business because lovebirds are the kind of animals that people impulse buy. You can get started producing your own birds, or you can also buy fingerlings and then sell the birds at a profit to other breeders.
