(update): Here it is (8hours old).
My father got an ostrich egg from one of his patients at the hospital. He was supposed to eat the egg, but he did not. He put the egg into the thermostat for 4 weeks and than into an old incubator. So now, small ostrich is getting out.
Prague Zoo told him, that if the ostrich gets out of the egg by himself, they will take it to the Zoo.
