HA, I knew you'd be hooked if the Dellie personality started coming through!
Hopefully, he will continue to be sweet and easygoing as most all the males I get out of Isaac are. Naturally, it's more of a crap shoot with hatchery stock, however, just a word of advice, if you don't mind. When he gets to hormone stage, over 12-14 weeks old, don't baby him even if it's tempting. Start giving him more space to just be a rooster and do his duties. You'll know what his personality will be once he begins mating the hens--even sweet male chicks can start up with human aggression once the hormones start flowing. If he gets to that age, upwards of 18-22 weeks old, and is still easygoing, you'll probably not have issues with aggression. Isaac's line was bred for temperament so generally, he produces males like himself, but nothing is guaranteed with roosters.
Congratulations to Odin on rating a name! Hopefully, he'll give you years of enjoyment.
