 ===== Introduction =====
-Every spring our residential  rooks and crows are getting excited, building beautiful nests and are laying eggs. Unfortunately, we then have to replace these eggs with dummy eggs, as we do not intend to let them raise unreleasable offspring in captivity. Howver, we encourage our birds in doing so, as it is part of their normal natural behaviour and life cycle, by providing them with all the nesting materials and nutrients required. All birds then sit on their eggs, with food being provided by their respective partners, until they eventually realise that their brood has failed.

 Most rooks and less commonly crows will at some point discard most of the failed eggs, and will then add selected toys from their enrichment reservoir in to their nest. They will eventually cover remaining eggs and toys with moos and soft nesting material. Both will remain mostly untouched for about two to three weeks. That is the moment when their grieving period starts…
