Egg Food is a great product for boosting the protein level of the glider’s diet. When a female glider is nursing a baby or two she needs 4 times the protein level that she normally needs, in order to produce the milk (syrum) that she needs for the babies. I am convinced that the greatest reason for a mother rejecting a baby is the low level of protein in her diet. She will eat much more of the Glider Grub and we normally supplement her protein with the Egg Food and/or with Pedia Sure which you can buy at any drug store or Walmart. We use the Vanilla flavor.
