I'm on vacation here in Biloxi MS and while sitting out back I noticed a bunch of grey squirrels (I was sq watching ) picking the green black walnuts off of the tree and not even touching the ones on the ground.. I brought Ike with me on vacation an he loves it here and adjusted very well!! I searched the tree and found a bundle of walnuts and picked them. Could I give these to Ike as-is? I saw all of the other squirrels picking them apart and discarding the green outer shell... and enjoying the heck out of the inside goodies!!
