Thank you Marcus! I really enjoyed reading this.
Although I agree they will learn from the older roosters, they must also do all these things by instinct. I have 11 chickens. All are 12 weeks old. They have no older chickens around to learn from. My top, lead rooster comes out of the coop first, then signals to the others to come on out. At the end of the day, he will literally round them up if needed to get them all back inside. Then he will enter last, and I shut the door. And he definitely spends more time on the lookout.
