Storks to Bring Their Own Babies?

It has been reported that at least 3 pairs of European white storks have constructed nests of twigs in oak trees on the Knepp estate in West Sussex in a conservation programme (https://www.theguardian.com/environment/2020/apr/26/uk-first-wild-stork-chicks-hatch-centuries). Eggs have been laid and it is hoped that the first chicks to hatch for centuries in this country will emerge. One must caution, however, that eggs were laid last year but they did not hatch.
