Hello! I have ONE call duck egg developing in my bator, and so the poor thing would not be lonely I ordered 6 babies from eFowl. The babies that are shipped will be 1-2 days old when they arrive. My questions are: Can I mix them all together right away? Can I do anything special for the shipped babies (food, supplements, vitamins, pro-biotics) to ensure survivability? Since they will be arriving the last week of May, I am hoping for decent weather temps so the babies do not get too chilled or heated. Thanks for all the help in advance!
