I had the privilege of meeting 3-day old chicks this week. I was captivated by their evolving social order. One baby was very bold. She walked right up to my hand inside the little warming pen, while the others ran in fear. Later, the lead chick - clearly the alpha chicken - urged others do what she wanted, and they dutifully complied. If you want to see hierarchy, watch a flock of hens! Even if they are tiny chicks barely out from the egg!
