Hi, we have a blue tit box in the side of our house that birds have appeared to nest and roost in for the last 3 years. Yesterday we installed a birdbox camera. Inside the box is a perfectly formed nest lined with feathers but no sign of eggs or eggshells so I'm wondering if maybe they never laid eggs at all. Should I leave the box as it is or should I remove the nest that is in there? I would welcome advice from all you knowledgeable people - I'm very new to all this š. Many thanks, Claire
