Yes, you'll have the standard 1/6 chance of uni twins IF you put a fertility wand on the mare before you breed her and you breed her to another pure uni stallion of the same breed at 6:23 GMT AM or PM.
Yes
There is no other way, The only way to have twins is by buying the fertility wand (or a pack with it).
You can't. It's not allowed on the game.
You can only produce twins by using the fertility wand on Howrse. There is no other way.
in order to get a uni on horwse you have to breed two uni's must be same breed, at exactly 6:23 or 18:23 game time.
Artificial Insemination for Howrse!! Lilcutey_2, PBS Horse Uni Breeder. Take a Look at my Page. =D
Yup
You have to have the fertility wand
I t doesn't matter. It could be am or pm
"Uni reject" is slang on Howrse for a normal horse whose parents are both unicorns. In order to breed a unicorn you have to cover your mare at 6:23am or 6:23pm GMT (that's 1:23am or 1:23pm if you live in the USA) and both horses must be unicorns. If you do all this correctly then you will have a 1 out of 6 chance of producing a uni. Breeding a uni is very difficult, so most uni offspring do not become unicorns.
You can't get twins without a Fertility Wand, unless there is a VERY rare glitch and you get twins by accident.
Unicorns were originally released through special events in the game.
