Does anyone have any idea why our extremely docile, loving female emu whenever there are strangers present? She doesn't try to attack the strangers she attacks us. I thought it was just when guys were here working (building things) that she acts this way but today she was crazed because my brother is here for the wkend at my mom's next door and she can see his truck. I had to fight her off with a rake! All other times she is sweet and loving, likes to be petted etc.. Any ideas? Stranger Danger! I have had her for @ 2years.
