Ok, these guys are 6 weeks old now. Some of them are obvious some aren't. Let's see if you agree with my guess.
First picture #1 Pullet, #2 ? I think it's a roo, but his comb isn't as big or as red as the others, but he's light colored like the others. #3 Pullet #4 ROO!
Second pic. #1 BO Pullet #2 This is the ? again. Roo? #3 pullet #4 Black Orp. Pullet
3rd pic. this is another picture of all of them for a better look.
Ok, what do you think? They won't pose for pics anymore, so this is about the best I can get.
