I have one hen that is pecking her eggs. First I thought maybe becuase they had a soft shell. Nope that's not it. I have three girls laying. The other two seem to be leaving their eggs alone afterwards. They also have oyster shell available to them. They have been laying for about 2 weeks now. I work two jobs most of the time and can't always check their coop throughout the day but I always do whenever possible. Yesterday was her first time laying in the nesting boxes but my dear hubby found the egg with a nice beak hole in it and the egg was perfectly good with no cracks. She layed it after I left at 4:15 to go to work. how do I stop it, especially when I don't know which hen is doing it.
