This is Lindy, a 5-week-old Silver Spangled Hamburg. She is a crazy chicken. Every time I open the top of the brooder she flies up onto my shoulder and sits there until I remove her. If I don't get the top of the brooder shut fast enough, the crazy little thing is right back up on my shoulder. Isn't she adorable?? She'll sit up there and nibble at my ear and hair and then will rub my face with her head. She loves it when I stroke her back or her chest and she will "purr" to me until and while I pet her. Is the face rubbing an affectionate gesture? Or something else? Or do I just have a really weird chicken?
