I have a pair of beautiful Netherland dwarfs who are 8 months old so have not yet experienced cold or frost. Every time I look out of the window at night they are huddled in the exposed outside corner of their run rather than upstairs in their bedroom (full of nice clean straw). I know they do go up there as two bunny sized dents appear soon after I change the straw.
Is it normal for them to stay up outside all night even in very cold temperatures? or are they down there because they are apprehensive? (we have a local cat who comes into the garden)
