Just a note to say, using a small mirror I noted we had chicks today. Hoping to get a better look and count later, but we did have five eggs, as of 5-16-14. Pretty cool to see this much activity the first year of mounting the box in our backyard.
Just checked on our active nest. Both adults were inside the box when I climbed up. Female flew out, male stayed inside while I looked. Saw 3 chicks. There were 5 eggs, maybe someone was under the male?
