I am new to raising chickens and have used this forum to answer the many questions that I have had. I purchased my first chicks on Good Friday of this year and got a couple of Silkies after that. I was able to distinguish the sex of my first chickens rather easy, however, it is more difficult for me to distinguish the sex of my Silkies. Below is a pic of them. The white one is 15 weeks old and the black one is 11 weeks old. I thought that the white one was a hen because it was four weeks old when I got the black one and it mothered it and still does, however, I sometimes think that it is showing some rooster characteristics. If anyone could give me their opinion about the sex of these two chicks I would greatly appreciate it.
