I have a white Leghorn hen who is 17 weeks and 6 days old. She laid her first egg but not in the nesting box. RIght on the floor of the coop!! Her second egg she laid the next day and it's shells were very thin and the raw yoke spilled on the pine shavings. The shell was very thin and it either fell of the roost where the hen laid it or it got stepped on by another chicken. What do I do?
