The little beakers are starting to look very grown up now, with adult feathers and only a few bald patches left. They will be leaving the nest in a few days.
Please read this: During a bitterly cold night, 4 of the chicks stayed out of the nest and perished. The video feed was cropped to hide the dead chicks, but the surviving ones are starting to move around now, so the video has now been uncropped, showing the whole box. Sadly, this is nature - lovely fluffy chicks growing up next to the bodies of their siblings.
