5 eggs

Every hour or so the female gets up, turns around and moves back, has a good stretch then checks on her eggs before carefully sitting back down on them. Today she reveals a fifth addition to the clutch.

The male is spending most days roosting in the other nest box (about three hundred feet away) but usually flies over and joins her at some point during the day. He does tend to sit right down in the middle of the nest box taking up all the space: not sure she appreciates this!
