ok...so i decided to go ahead and let her sit on some eggs. It's been about 3 wks now so they could start hatching any time now. Never done this before. Do I need to get chick feed?What will I need to get? How well can she take care of them and in what ways will I need to assist? They are in a raised nest box. How and when will they need to come down? Vitals...feed, water, warmth. What do I need to do? Thanks for your help
