Here's my silkie - she's 9+ weeks. Her name is Pearl but I'm not sure she's a female. In the morning she is sort of aggressive - she hops around the cage, hopping AT and ON the other girls! This was my first clue to question her femininity. After some online research, I found out that I should pay attention to the feathers on top of her/his head. If they're very full and round she's female - if they are thin and staggering lengths, he's male.... Maybe it's too soon to tell - but those feathers look male to me. Expert advice anyone?
