We've had a number of single chicks and they all wanted out sooner rather than later. Only had one female which was good, she REALLY wanted out of the nestbox and she was way too young to fly. One chick got his name because he wanted to follow his parents almost from hatching. His name was Sherpa because he kept climbing out of the nestbox - the first time a week before banding, so way (waaaaaaay) too young, even for a male.
