Breed

Once a dragon is fully grown, you have the option of breeding them with a fully grown dragon of the opposite gender. Doing so may produce an egg (or several). The egg will usually be of the same breed as one of the parents (the Geode dragon being the only exception as it can have Stone and/or Pebble parents).

Some DragCave creatures (paper and cheese dragons, chickens and all colors of dinos) cannot breed and others (like the pygmy, ochredrake and two-headed dragons) can only breed with others of their species.

Matching Dragons
Not all dragons will breed with other species. Two-Headed (AKA split) dragons and Pygmy dragons will only breed with dragons of the same species as themselves, and Ochredrakes will only breed with other drake subspecies. Also, when trying to mate dragons you may get the message, "The dragons don't really show much interest in each other," which counts as a failed breeding.

If the message, "The two dragons refuse to go near each other" appears, the dragons are incompatible, and will never breed. This is the default message when trying to breed rares with other rares.

The following breeds will not breed with each other or with another of their own breed, ever: gold, silver, ice, magma, thunder. These five also refuse to breed with Valentine and Christmas dragons (any year).

Vampire dragons cannot breed, although they have a Breed Specific Action called "Bite," which allows them to "turn" an egg of another breed into a vampire egg.

StoneXStone, PebbleXPebble, and PebbleXStone pairings may results in a geode egg. Stripes' offspring will take on the colouration of its breeding partner. If bred with another stripe, the colour of their eggs will be random.

Outcomes
Once you have found two matching dragons and bred them, they may produce between 0 and 4 eggs. These eggs may be of different breeds, such as half being the same as the father while the other could be like the mother, or all may be the same breed. You may only pick one egg out of the batch; the others will be abandoned automatically and can be picked up by others.

Breeding will have a better chance of being successful if there are few eggs in the AP.
