Hi I was wondering how hard it is to incubate mandarin eggs. Any harder then say call ducks? i have an old redwood, leahy favorite incubator works awesome and just set about 2 dozen white mandarin and normal mandarin eggs because the nest was becomming way too full. Do the ducks lay alot of eggs before they sit?? there was 14 egg and still no one was sitting in the box. strange or no?
