We just took in 20 laying hens that were headed for slaughter and in very tiny cages/ debeaked/ have massive feather loss. They are 1.5 and still laying. They have only been with us 2 days and I'm noticing all of their eggs are coated in calcium. They look identical to the picture in this article https://www.backyardchickens.com/a/common-egg-quality-problems. Should I attempt to change something or wait it out to see if it is just stress induced? Are the eggs ok to eat? TIA!
