So, my replacement flock of chickens is 11 weeks old. My wife and I have been working with them since we got them to socialize and get them friendly. They absolutely refuse to come when called, and still act frightened when I walk into their coop. IDK what else I can do? For weeks, when I go into their pen, I take a handful of meal worms and holler "chick chick chick" like I did with my other birds. The other flock comes easily when called. This has made our life easier, especially if I need to put them up quickly. These new birds are super stubborn. I figured by 11 weeks, they would be somewhat use to us by now!
I like that!
But, you are right, if older birds present it does make the younger ones more skittish and wary, and they tend to hang in their little group of same-age chicks.
