pulling hair out

Question
Yesterday i went outside to check out on my two rabbits and they were both pulling all their hair out. What does this mean?

Answer
It depends.  Were they pulling it out on each other or on themselves?  Were they fighting?  Is there fur everywhere or is it all in a neat and tidy pile?  

If there's fur everywhere and they were fighting, you may need to separate them.

If they are only pulling it out on themselves, you might check their gender if you've gotten them recently to see if they might both be female.
