They still look pretty young to be making any final decisions. Personally I like the second one better, his color and tail are better. As for the body, I suspect that he is maturing slower than the first and may fill out later, especially since he is the submissive roo. I would be inclined to separate the two Roos so that the submissive one gets a chance to be on his own. I suspect his confidence will increase along with his secondary male attributes! Do you have room for two pens?
