I have six banty BO youngsters that are ten weeks old. Two have pretty developed combs/wattles, the other four do not have much of anything...would I be right in guessing that the two are roos? Also, one of the roos is very aggressive with the other five and with the four std size Ameracauna girls that they room with who are seven weeks old (and the same size or larger than the BO). Several of the BO are looking a bit ragged in the feather department, and I suspect that the bully is 'roughing them all up when we are not around. My 8yo ds said that this is the case...and since he is our resident "Chicken Wrangler" I am going to go with what he has seen. I was thinking I need to rehome the bully, but wanted to get the opinions of some experienced chicken folk. Thanks for your help! One of the 7 week Ameracauna Tony "Bent Toe" the most aggressive one...he's a roo, right? Guido - also a roo, right? Victoria - the largest of the BO, no comb or wattle and the nicest feathering of the six.
