I have several silkies that are just coming up on 2 months old, I want to keep a few, but I don't want to keep ALL of them, so I would like to know what sex they are. Is there any way at this age to start guessing gender? I am new to them and so I have NO idea. I can tell the adults apart no problem. Any suggestions would be great. At this point I have several that are much bigger boned, and much bigger all around than their hatchmates. Does this have anything to do with it? Thanks in advance.
