I have a broody that is on 18 eggs now. there were only15 a few days ago, yet there is parts of 4 shells. No evidence that they were active. I am puzzled too. Are the other girls or Roo in the flock egg eaters? Ireallywanaknow...She sat on the first clutch of 8 about the 20th, they got marked with an X. They are still there.
