to tell you that the oyster shell for the duckies is on the way. I could only squeeze a little over 13 lbs in the box but it is coming your way. I put a huge trash back in the box and poured the 10 lb bag in and then filled it as far as I could. Hope the duckies enjoy...you can send part of the shipping only as I did not get the full 20 lbs sent. deal? The shipping charge is on the box, I forgot what is was.
