Are eggs given royal jelly or just larvae? Do the eggs need any nutritional substances to hatch? Or will an egg hatch in 3 days without any special treatment? So does a Queen cup with an egg in it progress to a Queen cup if royal jelly is added to it? So if royal jelly is not added to the Queen cup then does the larvae die? Will the hive make Queen cups with eggs and decide not to progress with making a viable Queen cell?
