I turned on the camera, inside the Box at 3am, and left it recording in the hope of seeing a egg being laid. After going through all the video, I could not determine when the egg was laid, however when the female left the box, I could see another egg.
She has been bringing in soft material and feathers. Each time I try to look, she covers the eggs over. Just how many has she laid. The average clutch for a Coal Tit, reading online, is 10. Will I find 10 eggs?
More in my next diary update.
