Baby Wild Rabbit Found very sick

Question
I found a very young doe rabbit near a burrow on a hot day. It was hardly moving and flies were cicirling overhead. It was evidently very sick. I decided to move it to my work place and put her in a box with water and grass. It's body was in an awkward position and it may have been injured by a predator, she was very weak. The next day it was out out of her misery by a co worker, I was wondering what was wrong with her? Would she have recovered, she didn't eat any food or water at all?  

Answer
Dear Ian,

Without a post-mortem exam, there is absolutely no way to know why the rabbit died.  It could have been any of a thousand different things.  I am glad she is no longer suffering, and that you had the kindess to protect her in her last hours.

Take care,

Dana
