I don't know what went wrong this morning, I have gone out to discover that my Mama hen has crushed her 3 day 20 eggs shells...one was out and is barely alive, she keeps getting up off them. I have done nothing to bother her in the past 3.5 weeks other than food and water given to her. She is in a nice secluded brooder box and was doing great. I can see movement in the other 2 shells, so there is life. What to do now? It is my first time allowing a Mama hen to raise them from eggs being hatched.
