When can you start to tell, I know they have the pea comb, and I have been reading about seeing three lines as a tell tell sign, when does that pop up? I have five little EE's, between 2 and 3 weeks old. There combs are more noticable, and I can see the three lines, but I don't know if it's just because they are about a week older than the other three, or if it's because they are boys. Trying to learn this myself so I don't have to ask you all every few days! Thanks, Julie I did get a few pictures, just haven't loaded them up yet, was mostly just asking for general info.
