Morning folks ....
One of the adults (Princess by size) was sitting on the edge of the nestbox until a wee bit ago. Can't tell if she has gone inside but doesn't look like - she's big enough that we should be able to see her outline no matter where she is in the box. At this age, the chicks don't need to be covered, they can thermoregulate on their own - barring a sudden freeze of course. In another week, the chicks will even be able to sit out in the rain without problems, but hopefully they won't need to ...
