I have 6 new girls that I introduced this summer. They are starting to lay now but someone (cant figure out who) lays an occasional egg and it is soft. Sometimes I find it splatted under the roost and sometimes broken in the nest box. I have found a couple intact also. My hens free range most days and have oyster shell available in the coop with the food nearby. I cant figure out who is laying the egg or why its soft. Do some hens never lay a hard shell? Is there something I have overlooked and should be doing for them?
