I have 17 hens in the chicken coop and chicken yard. We raise our own from 1-day old pullets and our babies are handled daily. They spend the first 6-8 weeks in the house and then out to their new home. My 10 hens that are 6 months old and laying eggs have become super friendly. Of course they squat anytime I am around, but I can pick up any of them and they love to be held and petted. I wrap my arm around their bodies with my hand being on their breast. They like to tuck their necks under my chin or in the crook of my arm. When I sit in a chair in their chicken yard it's like a little parade as they all take turns jumping up onto my lap for lovin'. They like to be petted on their backs, heads and necks. Sometimes they close their eyes and sometimes they make that purring sound. I frequently bring them little treats in the evening and sometimes it's just a little scratch. I searched this forum, but I didn't see much about others having such affectionate birds. I have all different breeds - RIR, Buff Orp, Sussex, Silkies, Aracaunas, Barred Rock, Black Australorp, Lite Brahama, Buff Brahama, Silver Wyan. I'd like to hear any other stories like this. Thanks!
