At 5:14 PM on February 23 Mary Lambright was on camera duty and saw Mom leave the nest – she zoomed in on the eggs and thought she saw several places where the owlet had begun to crack the egg. Is one of these cracks completely broken through?

“Pipping” is when the chick starts breaking through its shell using a hard projection on its bill called the “egg tooth”. The resulting hole is the “pip” that the chick enlarges to finish hatching. Young pip the egg and emerge without assistance from the parents.(1)
