I have a silkie hen just over a year old that always lays soft eggs and possibly no shell at all (a few times I've found only yolk in the coop). I feed Henhouse reserve mixed with flock maker, daily black soldier fly, they have free choice of oyster shell rocks and flakes, they have a big enclosed yard where they get sun, plus she's just recently had a round of poultry cell. What could possibly be her issue?? I'm out of ideas for this little girl
