Question
Working with rescued rabbits we often have people who purchased two girl (or boy) bunnies from a pet store or breeder, and a few months later they have a bunch of baby bunnies that need new homes.
I have heard this reported multiple times, in fact the majority of baby bunnies that enter the rescues in my area are the result of a spontaneous gender change of one of the rabbits. According to Wikipedia it is known to occur with animals as complex as chickens, but it does not mention rabbits.
Answer
As stated here, they don't change gender. Rabbits are one of those species whose gender is difficult to tell, especially in young animals, and therefore are regularly misidentified.
