Well.... a total loss. Two chicks dead, two eggs cracked and one in the incubator that if it hatches will be more trouble than it is worth. However, The hen still seems to want to set. I have built a more suitable brooder box. Should I let her try it again? Does she need a break? She seems to want to sit and is sitting in another nest box with no eggs. If it is advisable, this time, I will give her the eggs all at once so they should be synchronized. And the new brooder box is on the floor with a door so I can lock her in until she sets. And when the chicks hatch they can walk out to food and water and get back to Mama. .
