OK so she lays one with a shell then one without (showing that amazing intelligence by hiding the one with a shell in the hay barn and laying the shell-less one in the barnyard for the dogs) so do I just like, take my eggshells and break them up a little and put them in a dish for her...I am not sure how to administer them...she eats off the ground, never has been fed from a trough or dish so can I just throw the shells out with the feed or is it bad for the drake to eat the shells?
