Flopsy, Mopsy and Cotton-tail

While looking for worms in our dormant raised beds Jonas discovered a warren of rabbits.  They are tiny!  So small it's hard to tell what they are.  Their ears are flat down on their head and eyes completely closed; maybe 3 inches in length total.  Of course I'm now totally obsessed.  Unfortunately the only way to see them is to disturb their nest in the straw and dirt so I can't check on them daily, I mean hourly, like I'd want to.
