I have a silkie chicken who has been laying on four eggs. They all look fertile. She is in a nesting box in the coop with approximately 45 other chickens. My question is will she take care of them? What about food and water? We normally start chicks in the house when we buy them from the store but we were letting her do the "momma" thing. Should we take her and the eggs and place them in a separate area before they hatch or leave them alone?
