Ok, stopped by TSC today. They had 2 bins of assorted pullets that I learned were Red Sexlink, Black Sexlink and Brown Leghorns. Then they had a bin of straight run that are Speckled Sussex and GLW. I am kind of excited by these because they are different than what I already have. Plus, although they have a minimum purchase of 6 chicks, they said they would make an exception because I already have 6 and don't need 6 more. I haven't decided yet (at least that's what I'm telling myself) but....in the event I DO decide to get some, I would really like to get pullets. And my fear is that if I get one of each, one or both will be a rooster and if I get two of each, I might STILL not end up with a pullet of each breed so - from people who have these breeds, is there anything I can look for to determine gender? I.e., if they were sexlinks, I'd know how to tell but am not sure if SS or GLW have anything that distinguishes the gender in chicks <1 week old?
