We worked a lot with our oldest girls. 2 BSL, Orpy, 2 Barred Rocks, GSL, 4 Easter Eggers. Once they hit that teenage stage they wouldn't come anywhere near us. Now they are starting to lay and becoming very friendly again. They even let my 3 year old daughter walk around with them. Lol. A chicken under both arms and the rest of the flock following close behind. It's adorable. So keep at it. Spoil them rotten if you have to. They will eventually realize you won't hurt them...and have treats. (Blue berries, crickets, raw sunflower seeds, meal worms, and yogurt are my girls faves.) Good luck...and be patient.
