I'm new at raising chickens and guineas. I have a guinea pair and the hen has created a next at the edge of the woods. We just discovered it today 1/16, and there are at least 13 eggs in the nest. I don't know if or how they can be saved. We will have below zero wind chill at night for the next few days. The guineas roost in an unheated garage pen with the 6 chickens that I have. Help?
