THis is Mrs. Vogel, with our bottle babies, I add 1 egg to one feeding a day.  An older gentleman showed me that trick and said it helped with preventing scours.  I have noticed that is also helps to keep a shine to their coats.  Anyway, mine always loved it but I only gave them one egg a day, usually in the morning feeding.   Love the picture.  Also smart to break them to halter so you can lead them anywhere.
