Bluebird Chicks at One Week

Last week, I posted this photo of Eastern Bluebird chicks at about 24 hours after hatching. Here are two photos taken at seven days after hatching.
From skin and fuzz are growing feathers - well at least the very beginning of feathers.
There are four healthy chicks. All are about the same size. Photographed at 5 pm when all were sleeping and I guess well feed. Mom and dad were nowhere in sight. No sign of an unhatched fifth egg.
