I didn't see any BLRW threads in the first few pages so I'm looking for some expert advise. I have 6 chicks, straight run, who are now 6 weeks old. Purebred, farm raised, (not by me), but I am at a total loss as to what sex they are!? 4 look similar in shape, and comb size and color. Do all roos have waddles? Do hens get them? 3 are VERY aggressive, (stew), the 2 I think are hens seem very mild. I can't get pictures for a day or two, so any info on specific physical traits would be great. Or if you have some that you know are hens or roos, and are close in age, post a pic I really don't know what I'm looking at with these babies! Thanks!!!!
