You're cooking the egg yolk, right??? If so, it'll be unrecognizable even if by mistake an egg should crack and she sees the yolk inside. I found the easiest thing (when I was nursing my sick chicken with similar foods) was to si=ort of poach it: get some water simmering and crack the egg in and simmer till the yolk is just set. Then mash it all up together, white and yolk. I sometimes mixed a little yogurt or mushy feed in as well.
