TOOLS

Backyard chicken calculators

Five free tools for the real numbers behind keeping chickens: feed, flock size, eggs, space, and whether it pays off.

Your flock's real weekly and monthly feed cost, adjusted for free-ranging and season, plus whether your eggs beat the store.

Turn your household size into the right number of hens, with a buffer for molting and slow weeks.

How many eggs to expect from your flock per week and month, and what they're worth at your local price.

How much coop and run space your flock needs, adjusted for breed size and outdoor access.

See your monthly saving vs. buying eggs and how long the flock takes to earn back its startup cost.
