What a bachelor herd is
Frontier's Animals guide says mixed groups often have different male and female limits than bachelor groups, and that fighting and injury can break out when a group is too big or has too many males or females. The Zoopedia entries that list them give three sizes: the mixed group, the male-only group and the female-only group. For 53 animals the male-only group holds two or more males, up to 6 to 500 for the African Penguin; for the other 32 it is a single male.
Male bachelor herds you can release
Male Bachelor Herd is one of the release group types on the Zoopedia's Conservation list. These 16 animals list it: the African Savannah Elephant, Asian Elephant, Black Wildebeest, Blue Wildebeest, Cape Buffalo, Common Warthog, European Bison, Gemsbok, Lion, Masai Giraffe, Nyala, Plains Zebra, Reticulated Giraffe, Sable Antelope, Spotted Hyena and Thomson's Gazelle. The Zoopedia does not say how many animals a released herd holds, so the sizes in the table are for groups in your zoo. Which reserves each one can go to is in the Planet Zoo 2 release groups finder, and the release steps are on our Planet Zoo 2 Wildlife Reserves guide.
Female bachelor herds you can release
36 animals list Female Bachelor Herd, from the Aardvark, African Leopard, African Savannah Elephant, Asian Elephant, Binturong and Black Rhinoceros to the West Indian Manatee and Wild Boar. Pick “Released as a female bachelor herd” in the finder above to see all of them with their female-only group sizes.
Where surplus males go
When young animals grow up, some species push certain offspring out of the group. These outsiders only fight the others, so move them out. Where the male-only group holds two or more, surplus males can live together in a habitat of their own within that size; where it is a single male, that group holds just one. Healthy adults can also go to Storage at the Trade Centre. Which offspring leave for each animal is in the life cycle table of our Planet Zoo 2 breeding guide, and the Planet Zoo 2 habitat planner gives the space a group of any size needs.
Planet Zoo 2 bachelor herd questions
How do you make a male bachelor herd in Planet Zoo 2?
Pick one of the 16 species that list Male Bachelor Herd and move its males into Animal Storage. In Animal Trading & Storage, open Release Groups, choose Create Release Group, then the species and Male Bachelor Herd. Select the group, choose Edit Group Members to add the males, and finish with Finalise Release Group; the animals cannot come back after that.
What is a bachelor herd in Planet Zoo 2?
A group of only males or only females. Each animal's Zoopedia panel gives a male-only and a female-only group size, which can differ from its mixed group, and Male Bachelor Herd and Female Bachelor Herd are two of the six release group types for Wildlife Reserves.
Which animals can be released as a male bachelor herd in Planet Zoo 2?
16: the African Savannah Elephant, Asian Elephant, Black Wildebeest, Blue Wildebeest, Cape Buffalo, Common Warthog, European Bison, Gemsbok, Lion, Masai Giraffe, Nyala, Plains Zebra, Reticulated Giraffe, Sable Antelope, Spotted Hyena and Thomson's Gazelle. 36 animals can be released as a female bachelor herd.
How many males can live in a bachelor group in Planet Zoo 2?
It depends on the species. A lion's male-only group holds 2 to 5, an African Savannah Elephant's 2 to 5 and a Thomson's Gazelle's 3 to 36. For 32 of the 85 animals with these values, the male-only group is a single male.
What do you do with extra males in Planet Zoo 2?
Move them out of the family group: outsiders only fight the others. If the species has a male-only group of two or more, keep them together in a habitat of their own within that size; otherwise send them to Storage at the Trade Centre, or release them if the species allows a male release group.
