Are Flockmath's calculators free?
Yes. Every calculator on Flockmath is completely free to use, with no limits and no paid tiers. You can use any tool as many times as you like and bookmark the ones you need.
Do I need to create an account or enter my email?
No. Flockmath never asks you to sign up, log in, or hand over an email to use a calculator, and you can start entering your numbers the moment a page loads. The only optional email is our newsletter, which you are free to ignore.
How accurate are the calculators?
The calculators give planning-grade estimates, not exact guarantees. Your real results will vary with breed, climate, age, season, feed quality, and how you manage your flock, so use the numbers as a solid starting point and adjust for your own setup. For any health or welfare concern, check with a qualified poultry vet or your local extension service. You can read how we build and review our formulas on our editorial standards page.
What are the formulas based on?
Each formula is checked against guidance from university poultry-extension programs, including Penn State Extension and Mississippi State Extension, alongside established poultry-science sources. We aim for figures that reflect real husbandry standards rather than forum guesswork, and where sources differ we lean toward the safer, more spacious recommendation.
Do the calculators work for ducks, quail, and turkeys too?
Yes. Alongside the chicken tools, Flockmath has dedicated calculators for quail, ducks, and turkeys, covering housing or cage size, feed cost, and egg yield for each. Every tool uses figures suited to that species, since a duck's space and feed needs are very different from a quail's.
Can I use them on my phone in the coop?
Yes. Every calculator is mobile-friendly and runs right in your browser, with no app to download. The inputs are built for quick, one-handed use, so you can check a number while you are standing in the run.
