I just answered an ad for Free Chickens that are 8 Weeks old. I am going to get them today but need to know how to tell what sex they are. I have 7 girls now and would be adding the 6 Others to my flock will the 8 week olds get along with the older girls and how on earth do i know they are in fact girls.. and not roosters the person giving them to me SAYS they are girls but how do i know for sure. Also they are giving me 1 rooster i was going to let the rooster be free range while the others stay in a coop and pen. Will the rooster try to break into the girls.. please answer as fast as possible i need to know.. thanks Hey if you want to share pictures of your girls please help me out by supporting my FREE image hosting web site at www.freepixxhost.com its free to upload and i started it for all my friends!
