We ordered a straight run of 25 chicks (plus seven sexed pullets - 3 EE's and 4 Heavy Brown Layers for a friend). We lost two in the first week. We are starting to try to discern who is food and who is friends. So, please confirm my suspicions that the following are roos, also I'm going to list the breed I *think* they are, and if I'm wrong, please let me know that too! My guesses are based purely on combs, and I'm not assuming that if they DON'T have combs yet that they must be pullets, just suspecting these of being roos. They are 5 weeks today. #1 Barred Rock #2 Speckled Sussex (?) #3 Welsummer (?) #4 White Rock TIA!
