// go through all pens, check if they are empty and placed over a nestbox
// find female tame egg-layer who is not assigned to another pen and assign it to nestbox pasture
// maybe check for minimum age? it's not that useful to fill nestboxes with freshly hatched birds
// state and sleep setting is saved the first time autonestbox is started (to avoid writing stuff if the plugin is never used)
