The girls ruled in this group of nestlings. A male would stand at the hole rocking back and forth trying to muster that last needed bit of courage to leave the box. Each time a female would eventually push him out of the way and make her jump without too much hesitation. There were three males and two females. The first day that I watched, only the females jumped. They landed rather awkwardly down to the ground and ambled down the road towards where their mother perched above them. They toppled over as they walked, probably because they don't have that much room in the nest box to exercise their legs. Hard to say whether it was a good thing to be so brave. There was torrential cold rain the next day and a couple of days later, I only saw one of the females. The other one could have made it as well but I could not locate her.
