Hi all! I’ve recently acquired a backyard flock of 18 hens. They are fed high quality layer feed grown locally as well as free access to pasture, some scratch morning and eve, oyster shells, and grit. I’ve been adding Apple cider vinegar to their water daily when I give them fresh. Today I caught the hen laying the egg, absolutely no shell at all, and she stood up and turned to eat it. She appears healthy otherwise. She lays shell-less eggs whenever she lays. I usually notice yolk all over the nesting box she’s been in and on the other eggs in the box. What can I do to help this chicken?! She’s a red sexlink, one year old.
