I installed a new package 3 weeks ago that I have been feeding since the install. I continued seeing pollen & honey stores but no eggs, larvae or capped brood. Have not been able to locate queen so I purchased a new queen & she is still caged. Yesterday I found larvae after 3 1/2 weeks along with some capped brood. Should I discard the new queen that I purchased? Is there a possibility it is a laying worker? What should I look for to determine if it is a laying worker or my clandestine queen?
