You don't necessarily have a laying worker, evidence of a laying worker is multiple eggs/larvae on the sides of the cells as laying workers can't deposit eggs on the bottom of cells as their butts aren't long enough for the task.
When making a split where you want the colony to raise a queen from eggs/larvae, you need eggs/larvae first off for them to do so with. Larvae more than 4 days old are too old to use.
When preparing a colony for a new queen, kill the mated queen and leave them queenless 24 hours, then introduce the new queen, either direct or caged, your method of choice there.
Deformed wings could be a virus or varroa mite.
