Hatched eggs leave a number of egg shell fragments in the nest. From 1981 to 2003 samples have been collected from nearly all visited nests. Their thickness can then be measured by a digital micrometer. This method is an important supplement to the chemical analyses as thickness is related to load of DDT and other chemicals in the mother bird.

The collected addled eggs are prepared for chemical analysis. The analyses are done by the National Environmental Research Institute in Roskilde.
