What to write about

• A figure on the site that looks wrong, with the source if you have one — corrections are welcome.
• A calculator you wish existed for your flock.
• A broken link or a calculator that does not work.

There is no phone number and no street address — PeckCalc is an online tool, and email is the only contact route. All calculations on this site happen in your browser; nothing you type into a calculator is sent anywhere.
