The Breeding Facility is where the player manages their breeding program. It’s built from the Estate view and like other buildings, it has 10 levels. Every other level adds a breeding slot, and every other level makes the gestation time shorter.
A breeding slot is occupied when: two horses are mating, a mare is in gestation, or a foal is born and waiting to be sent to the stables.
Inbreeding
The player will be prevented from inbreeding horses too much. If a horse appears in both horse’s family trees, those horses cannot breed.
Mating
When choosing to breed two horses, the mare and stallion are first mating. Mating takes 4 hours, and during this time, the horses cannot be used for anything else. However, mating can be canceled at any time.
Gestation
When the mating is finished, the stallion is sent to the stable and can be used again, while the mare remains in the breeding facility and the gestation starts. During this time, the mare will rest and cannot be used for riding, training or other activities. The gestation lasts several days, but the wait gets shorter with a higher level building.
Recovery
After the foal has been born, the mare needs a few days to recover before she can breed again, but during this time she can be trained and competed as usual.
