I gathered most of my nuts last week, and its a good job i did as the
squirrels have cleared the rest.

They have left just the odd ones. I have picked these and cracked them
and found none have any kernals.

In checking some of my ones, I am at about 50% full to empty.

How can I check them without cracking them ?? and how do the squirrels
do it ??

PS

All my left over almonds have gone as well.
