Rabbits are cool, but they’re the only animals in Stardew Valley that cannot breed. This mod not only fixes that, but adds tons of customizations that allow them to become very profitable!
Your rabbits will have a base fertility of one, meaning they will have one birth every 1.5 seasons. Fertility of each rabbit is based on factors such as age, happiness, season, and friendship. If you keep your rabbits in top shape, you’ll be able to profit almost equally to pigs by selling their offspring.
The config file offers an insane amount of changeability, check out our guide on editing these files here!
Here is what can be changed, as explained by the author:
ignoreGender: if set to true, the rabbit’s gender is basically ignored. All rabbits can give birth as long as there is more than 1 rabbit on the farm. Otherwise you must have at least 1 buck and 1 doe.
accountForHappiness: if set to true, rabbits get a fertility bonus based on their happiness.
accountForFriendship: if set to true, rabbits get a fertility bonus based on their friendship with the farmer.
accountForSeason: if set to true, rabbits get a fertility bonus/penalty based on the current season.
accountForAge: if set to true, rabbits get a fertility bonus/penalty based on their age.
multiples: if set to true, rabbits can have multiple offspring at once. Litter size is determined by fertility.
baseRate: value determines the base fertility before bonuses. Default value 42 means it should take an average of 42 days between births before fertility bonuses are taken into account.
