Measure first
Use matching intervals
- Measure current eggs per minute without changing the setup.
- Use the live purchase cost and cash-per-egg value.
- Estimate or measure the after rate honestly; rerun when you have a real result.
Should You Buy Another Chicken?
Compare the wait, added production, and payback using only values from your current farm.
The working Chicken Farm purchase calculator uses your current cash, purchase cost, before-and-after egg rates, and cash per egg for payback. For a Chicken Farm buy-or-merge decision, compare that gain with the production sacrificed by the complete merge tree.
Measure purchase payback
Enter current values from your game. The calculator contains no fixed prices or production rates.
Buy or merge
Compare the opportunity cost
A purchase adds production; a merge may consume several producing chickens. Compare payback with the full merge-tree requirement before choosing.
Questions
Purchase calculator FAQ
What does purchase payback mean?
It is the purchase cost divided by the extra cash the new production adds each minute.
Why does the calculator show no payback?
The after-purchase egg rate must be higher than the current rate. Recheck both measurements over the same interval.
Should I always buy when payback is short?
No. Also consider a merge, a planned rebirth, and whether the current purchase detail may change.
Are prices built into this tool?
No. You enter the live cost, cash, egg rates, and cash per egg shown by your current game.
