Hello! I have four hens who are about nine months old. Whenever I reached down to pet three of them the fourth stretches her neck then runs at me and starts to nip at me. She seriously almost draws blood- she’s a giant lavender Orphington. I usually brush her aside with my foot when she does it but now I’m going to start training her like a dog I guess- saying NO loudly and push her away? ? I read some of the other posts on here about this but I feel like she really is trying to protect the flock and thinks that I am threatening the other hens when I try to pet them or pick them up. My other birds are seriously mellow and very calm when I pick them up or pet them but she loses it! What to do? Is this normal? She has flown up to my shoulder before during one of these episodes...pics of her below.
