Uncommon Egg hatch rates and pets
The Uncommon Egg can hatch 4 different pets. Below is every pet and its exact hatch rate, so you can see what you are really chasing before you spend time or Robux. Each hatch is independent: the odds never improve from past misses.
| Pet | Hatch rate | ~1 in |
|---|---|---|
| Black Bunny | 25% | 1 in 4 |
| Chicken | 25% | 1 in 4 |
| Cat | 25% | 1 in 4 |
| Deer | 25% | 1 in 4 |
Rarest pet
Deer - 25% per hatch
On average that is about 1 every 4 hatches, and you need roughly 9 hatches for a 90% chance of getting at least one. Plan a budget before you grind.
Open the hatch odds calculatorHow to use these rates
Hatch rates are per-egg chances, not guarantees. A pet listed at 1% still has only a 63% chance after 100 hatches. Use the Uncommon Egg's rarest-pet odds above to decide whether to hatch for it or trade for it instead, then check the pet's full stats and value before you commit. If you are comparing two pets from this egg, the pet comparison tool lines them up side by side.
