I have a Midget White hen that is currently hatching eggs. When I checked her earlier, it was obvious that an egg went bad and broke. The whole nest and eggs was a stinking mess. I changed the nesting material, but left the eggs as they were. There are 11 that are pipping. What would be best? Leave the eggs as they are or wash the shells before zipping begins. The hen is a pet and I can do whatever I wish without too much trouble. Is the nastiness a heath concern for the new poults?
