Still Queenless?

Checked all the colonies to establish whether or not 4 of the 5 were really queenless. Two of the 5 appear to have queens since brood in all different levels of development were observed. The other three seem to be queenless, of which one has a drone layer. Will again inspect these queenless hives next week to see if there is any change. Hive 1 Brood present. Active colony. Hive 2 Still no eggs/brood. Hive 3 Brood present. Active colony. Hive 4 Still no eggs/brood. Hive 5 Still plenty of drone brood.
