When I switched from crumbles to pellets the girls stopped laying for 13 days.  Chickens do NOT like change, any little thing will set them off.  I have had them stop over a change in food, a change from shavings to straw in the nest box, and addition of more hens, and even missing a day in letting them out to play.  I think it is their way of throwing a temper tantrum.
As for the molting wait a week or two after they finish and I am sure one of those little eggs will appear.
I am also hoping that the rest of my birds will start laying. I have five that are older than 25 weeks and are not ready to lay. I have 9 approaching 20 weeks that I would really like to see some eggs from. Maybe we could have your girls race my girls and see who will lay first. LOL
