Three weeks ago I set a broody hen on 12 eggs. She kicked two out and after a few days of them being on the side I removed them. Today is day 21, but it was kind of late in the day so I am thinking tomorrow is the more likely hatch date. However, she moved around today and I saw that there were only 7-8 eggs there, so 3 or 4 have gone. The coop I am sure is secure so I don't anything has gotten in. I have read about broody hens eating their eggs, but would she have eaten the shell as well? Thanks for any advice.
