That brings up an interesting question, what is the reason for the carrying on? Complaining to get the nestbox occupant to hurry up and leave? Or at least announcing the intention and need to lay, maybe in order to secure a spot "in line" for it, or announce you're next so anybody else has to wait? If there is no one in the nestbox she wants, did Phyllis still carry on?
Now she has her Secret Garden, and no competition at all, but it is not a safe secure place like the coop, so there's an extra need to be quiet.
What do you and everyone here think?
