How does the merge calculator work?

It raises the merge size to the number of tier steps, then calculates missing chickens, total merge actions, and surplus.

What merge size should I enter?

Enter the requirement shown by the current in-game merge prompt.

Why must target tier be higher?

The tool plans upward merges, so the target must be above the current starting tier.

Are chicken prices built in?

No. The merge tool needs counts and tiers only; the purchase tool accepts the live cost separately.
