I have had lots of bulbs disappear: tulips, gladiolias, oriental lilies, crocus, and probably some others that do not come to mind at the moment....
Those look like daffodil bulbs and they are highly poisonous. I have chickens dig them up, but never eat them.
Hi Jan, I know you from BHG... :) I am originally from Pennsylvania, just wee bit south of NE. I live in Missouri now.
