Same group, one hen eating her eggs!!!

[jt673]

I just noticed that one of the hens that we inherited with the coop we bought was eating her egg this morning. Is that stress from the coop move? The other NH red one in with her only ate the yolk but not the shell. How can I discourage the one who laid the egg from doing this short of checking the nest boxes every hour in the morning. Some of the flock that they were used to being with were taken out this morning before this happened because it was overcrowded. Is she sressed from that as well? Would that cause her to eat her egg?

We really would like to keep her and want to calm her down. I also noticed that she had her mouth open and wings drooped a bit from her body after I discovered this and took the egg away. Is she stressed, hot from hormones??

Thank you in advance!
