I've only had hens since July. We got them as week olds and have handled them daily so they usually allow us to hold them and pet them. Alice the friendly chicken is a brown leghorn who seemed to like the attention the most. She has always pecked gently out of curiosity but last night after letting her out of the coop, she stalked my legs and pecked me hard on the hand when I went to pet her. this morning she followed me around the yard and pecked at my legs and tried to jump up on me and scratch me with her feet. What is up with her? She has not yet laid eggs. I have a light in their coop giving them at least 14 hours of light a day.
