It's a duck egg. We brought it inside and put it on a heat mat. The young one looks like it has an egg tooth and is moving it's bill open and licking its bill. We were worried that it would get further damaged if we returned to the disenchanted mama duck (mad that we moved the eggs to candle) so brought it in. Should we run out and get an incubator (20min away?) I know we shouldn't give em too much help with the egg....but any advice? The whole egg is flexing with the breaths. help!!
