I have had 2 eggs that have been dropped from the roost bar before I let them out in the morning. Apparently this hen, a black sex-link, hasn't gotten the idea of nesting before dropping her egg. I don't know if she is dropping them at night when she is too drowsy to move, of the hour between sunrise and when I let them out. The shells have been soft, they have free choice oyster shells but don't seem to eat as much as I would think they should. The first one had a blood streak on the yolk. Mostly I'm concerned that she is not making an effort to nest.
