Week 1 chick behavior

I thought you might enjoy a photo journey of our chicks' growth over the first week of their lives.  This photo is a chick fresh out of the hatchery box (probably day two or three of its life).  At this point, they were pure fuzzballs who spent most of their time sleeping under the light.  Heat was critical, and they got easily chilled by even slight changes in temperature.

By day two, one of the chicks had learned to scratch in their feed dish.  On day three, I noticed the first one hopping up onto our homemade chicken waterer's mount to roost above the crowd.

In the second half of the first week, chicks began to show a bit of dominance behavior, run-flying at each other to see who would back down.  They became more active and spent less time sleeping under the light (and seemed to need the heat less.)  I stopped worrying about them dying, and they all grew in wing feathers.

I wonder what week two will bring?
