We have been monitoring 10 kestrel boxes for the past three years with two pairs nest among these 10 boxes. This year one of our parents produced 5 eggs (like normal) as first indicated by us on 5/30. However, since then we have not seen these eggs hatch. At this point we are far beyond the normal incubation hatching period indicating that for some reason these are not viable. This momma kestrel is particularly protective too and is still attempting to incubate. My question is, what to do next. Do we remove the eggs to give her some time to grieve and reassess? Or do we leave them for her to eventually give up on? She rarely leaves the box on checks (done with an endoscope camera). Our other nest did extremely well and gave us a record of 6 eggs to chicks to fledglings.
