I'm old. I'm easily distracted. I'm forgetful. Sometimes, I'm simply unable to stay awake any longer as we, both the unborn chick and I, have been awake ALL day and night trying to get the little one hatched. Those long hours aren't good for the old ticker when you get to be my age.
The touch of oil trick has been a life saver (for the chick), and sanity saver for me. The oil makes the membrane completely see-through, helping me determine both the condition of the chick AND how rapidly (or not) that the veins are thinning out. It helps me make critical decisions on how to proceed should the hatching continue to be fraught with misadventure.
