I leave bones down and tend to find they eat all the good stuff in the space of a day, the outter ;part of the bone I just leave until theyve finished with them. Which could be a week or so.
Never had any issues as by the end of the first day theyve cleaned them of any meaty bits and marrow so only the bones left. So no upset tummys here!
I wouldnt refreeze them personally, but I'm sure they'll be lots of different opinions on the feeding of bones :-D
