Well, I, for one, am resisting the urge to over analyze the feedings. I suspect Beauty is very well aware there is another female in the territory and that Dot.ca has been with her. My thought is she may be adjusting her usual parenting to account for that and assure the best chance of survival for her eyases.
And one more edit-just as an FYI for new followers-newly hatched eyases do not need to eat for 24-48 hours. They get all the nutrition they need during that time from the yolk absorbed into their abdomen just before hatching.
