Well, I guess my reporting job is over and I will miss doing this. All chicks have left the box. Got some screen shots of the Male Fledgling attempting to enter the box and have posted on Flickr- http://flic.kr/ps/2dtbqo- Like anything else though, I couldn't figure out why they didn't post in order.
Busy morning. Female chick finally rested in cavity. Lighting not good outside yet but I believe it was the male fledgling that came to sit on top of the box. Then both mom and dad flew around the box. The male then left and now we are back down to the female chick resting in the cavity.
Food was brought and one female grabbed it. The other female attempted to get a share. They went around the box a couple of times before the 2nd female grabbed and got a piece. Then it was tug of war until a piece broke off. Both females ate some then
