Help!!! I just started rehabbing a 4 week old baby flying squirrel and I’m reading a lot of info about the homemade goats milk formula but I had someone tell me egg yolk would for sure kill my baby. Can anyone give be advice on this? She’s in great condition. Goes to the bathroom frequently, some days a little less pooping than others but still goes fine. The formula I have been making is 3 tablespoons of goats milk, 3 table spoons of dannon whole fat yogurt, and half an egg yolk.
