Rex (E1) looks like s/he is almost fuzz free now. Almost all the feathers are in now. Looks like the other two have caught up in size too. Ackos, I think your right... in a few days it will be hard to tell them apart.
I think he is going to have to go back to the wide angle, too much going on off screen
Or just zoom out more with this camera (if they can). The only problem with the wide angle cam is the big splotch in the upper left corner. I'm not sure if the rain has, or even can clean that off yet. That cam has a hood over it so I wonder if it will ever wash off this season.
