There is a lot of controvercy about the pros and cons of bottle feeding vs. Mama. Have you ever pulled one of the two twin fawns to bottle feed and then compare its progress vs. his or her twin with Mama. My limited experience has shown me it dependes a lot on how smooth the transition goes for the pulled fawn and how healthy it stays until weaning. I have seen some temporary stunted growth that takes as long as two years to "catch up". In a worst case scenario I had a policeman bring me a 2 to 3 week old wild fawn that took a couple of weeks to finally take a bottle. She is now 2.5 yrs. old and is still only half the size of other wild adult does. As a matter of fact when she lost her fawn coat, she grew her winter coat and has NEVER shed in the summer. It just stays the same. What have you experienced? Tom
