I have a little hen who is definitely a hen (watched her lay an egg one day) who, soon after I came back from a trip to AK, started becoming aggressively assertive to me and attempts to mate my foot and hand just like my roosters mount the girls! It's very, very strange and I can't find any explanation. She used to be super sweet and would fall asleep in my hands, however that now appears to be the opposite of her intentions. What's going on??
