Hi, I have a small mixed flock of 3 GLWs and 2 BOs, all hens. The Wyandotes are flighty and won't let me get near them. The larger of the Orpingtons is friendly, but not "lap chicken" material, which is fine, but the smaller one has become aggressive toward me and my DH when we open the coop to feed or water them. She'll eat scratch feed out of my hand but if I reach in for the feeder or waterer she raises up and puffs out and will aggressively come after me. I've tried just pushing her away, but for the last couple of days I've had to be real forceful about it. She's not aggressive with the other hens, just people. Any ideas? They are almost 7 months old and haven't started laying yet. Thanks for any feedback.
