Hello.. we hatched 11 rir hens this spring and they are just starting to lay. Today when i was walking by the fence i noticed one of the hens running with something in its mouth and the others were chasing her...turns out it was the shell from a soft shelled egg... this happned twice today. I know that eating eggs is a bad habit. I am almost positive that the soft shelled eggs were not layed in the nestbox.i do have oystershells for my hens and i did put plastic eggs in the nest boxes so they would knowj were to lay. I dont want to have problems with egg eating hens...what should i do?
