If the hive is acting normal, give it a little more time to see if she may start laying. I did have one of my trap outs lose their queen and I had another that took 4 weeks to start laying. I put in a frame of eggs in both hives and was very confused as to why they weren't turning any of the eggs into Queen cells in one of the hives. The a week later there were eggs and larva.
After taking off one of my trap-outs prematurely I follow Iddee's recommendation of at least 6-weeks before removing the cone.
