About Flock Figures

Flock Figures is an independent site of free planning tools for people who keep chickens, ducks and quail in their backyards. Hobby flock owners often face the same small math problems: how big a coop to build, when eggs will hatch, how warm the brooder should be this week, how long a bag of feed lasts. We built a fast, ad-light tool for each one.

How we build the calculators

• Published sources first. Each calculator's defaults come from university extension publications, which are linked at the bottom of every page.
• Show the math. Every page explains how the result is calculated, so you can adjust for your own situation.
• Private by design. The calculators run entirely in your browser. We don't collect what you type.

What we're not

We aren't veterinarians and this site isn't veterinary advice. For sick or injured birds, contact a poultry vet or your state's cooperative extension office.

Independence
