Okay - age ol question... I am going to look at some chicks tonight - person has no clue about gender - thinks most are barred rocks and mixed breeds - they are about 4-5 weeks old. I know there are no guarantees - but what are some traits that I might want to look for to try to get mostly hens at that age? Since I really want pets - I will be mostly looking for ones that come to people - but wondering if there might be somethings to look for? Would love all input!
