My chicks are 4 weeks old tomorrow. When do you think I should be able to sex them? Thanks everyone!! I will try and take some pics but if anyone has any tried and true "the feathers are like this on a pullet and like this on a roo" or anything to do with the combs I would really appreciate it. I simply have no patience!!! Why didn't I order a certain number of hens and a few roos? Newbie learning curve!!
