Breeding & Hatching

There are two ways to grow your team: hatch new fighters from eggs, or pair your best birds to raise an even stronger next generation. This is the heart of the long game.

Hatching eggs

Every fighter starts as an egg.

Where eggs come from

  • The shop sells one egg for each bloodline. A Bocky egg is the cheap starter; the six elemental eggs cost a bit more.
  • The Breeding Room creates special eggs from two parents (below).
  • Daily rewards sometimes give eggs too.

Open an egg with the Hatch (Activate) action to turn it into a fighter.

Every hatch is a little surprise

  • Each new fighter is born with two unique traits.
  • There's a small lucky chance for bonus starting stats — even a cheap egg can hatch a star.
  • Boys and girls start a little different: males lean toward power and health; females lean toward speed, luck, and dodging.

The Breeding Room

Pair two great birds to make a greater one.

What you need

  • One male and one female of the same bloodline (no mixing breeds yet).
  • Both must be grown up but not too old — adults from 15 to 49 days. Birds 50+ are too old to breed.
  • Both must really like you — at least 80% happiness. Pair up birds you've cared for well.

The egg they make

Before you confirm, you'll see a preview of the baby's possible stats and traits. The egg inherits from both parents' current stats and traits — so a baby from two well-trained champions starts far ahead of a shop egg.

Cost & waiting

Breeding costs coins — stronger parents cost more because they make better babies. After you pay, both parents rest in the nest for about one day. While nesting they're safe (no hunger or happiness loss) but can't fight, train, or be fed.

Breeding coins don't come back

The breeding fee is paid up front and isn't refunded, even if you cancel. You'll be asked to confirm first — so pick your pair carefully.

Building a bloodline

  • Train before you breed. Babies inherit current stats, so the more you train the parents, the stronger the egg.
  • Aim your traits. Good traits pass down, so breed birds whose traits you want to keep in the family.
  • Keep them happy. You need 80% happiness to breed — pat and feed favorites in the days leading up to it.
  • Watch the clock. Birds can't breed at 50+, so don't wait too long with a great pair.
