Two gay families of storks in the Netherlands have successfully raised families, in what is expected to set the debate over gay parenting flapping.

A gay and a lesbian stork couple were given an egg each at the Dutch zoo in Overloon, and despite fears that they may not pay them any attention, both hatched successfully.

The zoo said the birds took to parenthood straight away.

Zoo spokeswoman, Esther Jansen said: “The gay storks look after the eggs and the chicks just as well as our heterosexual birds.”
