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!
