I have a beginners question. I have several young roos obtained from different sources. To me it looks like they are going to be to "normal" looking as far as haveing the straight up back I see in others birds. Are the young supposed to be like this? Will they straighten up and stand more erect as they get older? They are beautiful and I love them but don't want to be embarrassed by haveing someone point out a really bad flaw when I show them off . I have heard or read the term" long in the back" is this what is wrong with them. Is there any way to make them stand more erect?
