How to Use the Egg Hatch Speed Calculator
Quick Start Guide
- 1Select Egg Type: Choose the egg you want to hatch from Common to Divine rarity, or use Custom Time for special eggs
- 2Add Helper Pets: Select up to 8 helper pets with hatch speed abilities like Chicken, Rooster, or Kiwi
- 3Configure Pet Values: Adjust speed bonuses, time reductions, and intervals to match your pet's actual stats
- 4View Results: See your optimized hatch time, time saved, and efficiency metrics in real-time
Pro Tips
- •Rooster Power: Multiple Roosters multiply their effect, making them excellent for very long egg hatches
- •Blood Kiwi Efficiency: Blood Kiwis provide both speed bonus and time reduction, making them the most efficient single pet
- •Bald Eagle Timing: Bald Eagles are most effective on long hatch times where their periodic reductions have more opportunities to trigger
- •Pet Combination: Mix speed bonus pets (Chicken/Rooster) with time reduction pets (Kiwi/Eagle) for maximum efficiency
Egg Hatch Calculator FAQ
What is the Grow A Garden Egg Hatch Speed Calculator?
The Egg Hatch Speed Calculator helps players optimize their egg incubation times using helper pets. It calculates the exact hatch time based on your active pets' speed bonuses and time reduction abilities, helping you plan efficient hatching strategies.
How do helper pets affect egg hatching?
Helper pets provide two types of bonuses: speed bonuses (like Chicken's +10% or Rooster's +20%) that reduce overall hatch time, and time reduction abilities (like Kiwi's -25 seconds every 60 seconds) that periodically subtract time from the remaining duration.
Which pets are best for egg hatching?
Blood Kiwi is the most effective single pet with +20.4% speed and -45.9 seconds every 59.4 seconds. Roosters are excellent for multiplicative effects with +20% speed each. Bald Eagles provide powerful periodic reductions for very long hatches.
Can I have more than 8 helper pets?
No, the game limits you to 8 active pets total. The calculator enforces this limit and helps you find the optimal combination of 8 pets for maximum hatching efficiency.
What's the difference between speed bonus and time reduction?
Speed bonuses (%) apply continuously to reduce the overall hatch time, while time reduction abilities subtract fixed amounts of time at regular intervals. Both stack together for maximum efficiency.
How accurate are the calculator results?
The calculator uses the exact game formulas and mechanics. For abilities with chance components (like Bald Eagle's 70% chance to double), it uses average values to provide realistic estimates of your expected hatch times.
