it must be hard birthing a unicorn

What if they're born without a horn, and only grow it after birth?

I guess we will never know?

It's like a bull.They are born with smooth nubs.

The unicorn mother dies upon giving birth as the infant rips its way free of the womb. Hence there aren't many around anymore. Some people even think they don't exist because they're so rare.

Did you never watch the OLD My Little Pony? They grow horns after birth duh~

Like a rhino calf only grows its horn after a year

Why's it got human tits
