Hi, my tame male guinea (about a year old, in coop with sister and 3 chickens)has become Godzilla when men (that he has known all his life with no problems before) enter his space. He attacks from any angle. He tried it with me once, (I'm female) but mostly we get along very well. When he does get the evil eye, I talk to him or sometimes resort to chasing him a bit with the rake. I'm guessing hormones and things are kicking in. He bullies the chickens every now and then, especially when the 'mood' strikes, but when I let them all out, he stays with them, does not want to go on his own or with the wild guineas (one wild one did give a good dose of his own medicine!). When the chickens have a good cackle, he joins in with a very cute attempt at cackling too! (He does the normal guinea squawk at other times) But it is so odd that he has this problem with human males (although I'm the primary caretaker at the moment, and the one who raised him,, and no other Women around, so perhaps that has something to do with it?. Is he protecting his 'girls' (the one time he did go for me was when I picked up his sister, although she has no interest in him), just being a young male, or all coincidence? I love the bird, but can't have this behavior. Unfortunately he shows no interest in leaving the chickens and joining any other guineas. Apologies for the essay!
