I have 3 Swedish blacks that are 5 days old. They are super lively and cuddly. I am worried about the smallest, Pepper Ann. She eats, but not as voraciously or even close to the quantity that her sisters do. They are on a diet of Un medicated chick starter with a sprinkle of nutritional yeast mixed with goats milk to make it mushy. They got scrambled eggs with parsley as a treat today. I am a first time feather mama. Am I being silly or should I be worried about her?
