my hen has nine eggs. 1 has hatched and 1 started to hatch...next time I checked on her the cracked egg was missing. Not even the shell was there. Snake? rat? That was 4 days ago. All the other eggs have not hatched yet and now mama is up and walking around with her baby in tow. Will she go back and sit on the eggs? Are the eggs going to hatch if she doesn't sit ALL the time? So many questions....HELP!
