sleeping arrangements

Hi y'all,

Our nights are getting cooler and I worry about my two boys getting
cold at night.  The hutch is free of draughts but it is on the grass
which is quite damp come the mornings.  I have been "wrapping" the
entire hutch at night with a tarp to keep some warmth in.  The nights
will get even colder as our winter comes on.  What does everyone else
do for warmth?  I remember Ted said not to put in towels or blankets
as they harbour bugs and are a hassel to keep clean.  She wasn't wrong
concidering the amount of poop and wee is ac***ulated!
