We have read that in one part of Germany, the second egg is taken from LSE nests and incubated elsewhere, and those chicks live to migrate successfully.
Yes, I have heard, that they take out the second chick and raise it for some time until it has a chance to survive, and than put it back in the nest, where the two can grow up.
Yes ornithologists do that, when there is possible extinction in question.
As Urmas said, LSE species isn't under such threat in Estonia.
I 'googled' about saving both (all) eaglets and found this:http://simonthomsett.wildlifedirect.org/tag/eagle/
scroll down till 'Goodbye Vero's':
"/.../ Most eagles lay two eggs, 3-9 days apart. They hatch asynchronously with one being very much more robust than the other. The larger individual will almost invariably kill the younger sibling. The younger sibling has a miniscule chance and that is to kill its old sibling. Only one chick survives. /.../
/.../ If you take one chick away immediately at the hatch of the second chick, you can raise it in captivity, and produce twice as many as otherwise would be the case. But the hand-raised chick you kept would be a human imprint. /.../
/.../ When it comes to Abel rescue, I developed a technique that made sense but was physically demanding. Raise the chick in captivity for 10 days, take it back to its parents, swap it with the “wild” sibling. Take the “wild” one back. Raise that for 10 days. Take that back. ETC. Do this until they are 8 weeks old when they are large and nearly ready to fledge. Put them together and although they fight, they are equal combatants./.../ "
