I have a chicken that lays a softshelled egg at least once a week. My questions are: How do I figure out which chicken it is if at all possible? How and why is this chicken laying softshelled eggs? And I have a chicken that seems to breaks the egg when it goes into the nesting box and eats it. When I gather the eggs and their is yellow stuff all over the eggs in that nesting box I knew what happened, because sometimes I even find some of the egg shell not eaten. My chickens are free range chickens so they get grass, bugs, and I also have shelled corn, oystershell, grit and fresh water for them to eat anytime they want, and I also give them bread once in awhile for a treat and dig up worms for them as a treat. So, if anyone has any suggestions or any ideas of what is going with my chicken please tell. I would appreciate it. I always thought they just layed softshelled eggs when they begin to just start laying eggs. I am still learning new stuff all the time about chickens.
