because, when breeding a unicorn, you could get really lucky and produce unicorn twins! or if not, you get twin horses and people like a 2 for 1 deal.
You can only produce twins by using the fertility wand on Howrse. There is no other way.
You have to have the fertility wand
There is no other way, The only way to have twins is by buying the fertility wand (or a pack with it).
The meadow will regain fertility
fertility will never get higher it will always decrease depending on how often people use them or you grow crops in them. The cleanliness will increase though, less often in the winter. ~animalslover ( animalslover on howrse too)
Giving a friend a fertility wand allows them to produce twins with one of their mares.
WikiAnswers is not the place to ask for items for games, it's a place to ask questions that anyone can make use of (example: "How do you get a Fertility Wand on Howrse?"). Sorry!
If you are talking about the calender, I got a fertility wand.
Go to the Black Market and click on Fertility Wand. Choose the mare that you want to put it on and click purchase with a fertility wand from my stock.
Fertility will rise daily from when you put the meadow into use. A 50% fertile meadow however can never become 100% fertile.
This is what the Howrse E.C. help recommend (The answer was long so I picked what I thought was the most important): To restore fertility, you must let the meadow lie fallow. However, the meadow can only be restored up to its fertility level at the time of purchase. A meadow that was not fertile to start with will therefore never reach 100%.The fertility of a meadow increases by 1% for each day that it lies fallow in spring or fall, by 3% in summer, and by 0.2% in winter. Land that lies fallow in winter will only slightly increase in fertility.
You can't get twins without a Fertility Wand, unless there is a VERY rare glitch and you get twins by accident.
