A nutrition enthusiast is weighing the pros and cons of keeping a few chickens in his backyard, reasoning that eggs that he doesn't eat he can sell to friends and neighbors. One trip to his local hardware store later, he returns with $560 worth of lumber, paint and carpet and a weekend of fun assembling a chicken coop. He starts small, and invests another $20 in two barred rock and two Buff Orpington hens. A 50-pound sack of layer pellets costs $12 and water is essentially free. Much to his dismay, his doctor tells him his cholesterol is high, so he elects to sell all of his eggs to raise money for a popular statin medication. It takes the four hens a month to work their way through the sack of feed and during that time he collects 84 eggs, which he sells for $5 per dozen.

What is his profit the first month?
