Interesting article, though commentaries are disturbing.

For what I know, zebras are very nasty characters, always fighting, biting, kicking each other.
That leads to often scared trophy rugs.
When I was looking for 2 zebras (I have 2 kids) Buzz Charlton insisted that it was best to look for a male group. According to him, should the dominating male of a mixed group be killed, females refuse a new "husband" during 2 years. What curbs down the fertility of the herd.

Your opinion?
