Off and on since we returned from vacation I have been watching the bluebird house. When we left there were four perfect blue eggs in the box. Upon returning two weeks later, there was a pile of bluebirds and I couldn't tell if there were 3 or 4. They were obtaining their flight feathers and seemed to be healthy. We had put up a wren guard after the female's first egg disappeared and she laid her second egg. We would have had five had the first one not been stolen by a wren. The wren guard covers the hole but leaves enough room between the guard and the house to allow the bluebirds to slip in. If the wren doesn't see the hole, he ignores the box. And it worked splendidly. It took 30 minutes for the bluebirds to figure out how to get inside. When we got home, we removed the wren guard. The babies should be at least five days old before you do that and ours were.
Today I have noticed activity in the box that I can see through the entry hole and I suspect our babies will be leaving us soon and I will be able to tell if there is an unhatched egg. They will spend several days around the house being fed by mom and dad before they all move away. We see them through the winter checking out the boxes which they seem to select far in advance of nest building. We start making sure the boxes are in good order in early March, they have been known to build nests in April but it's usually later. It will be sad to see them go, they bring me great joy.
Off to the vet....
