I agree with handling him a lot AND I think what someone said about letting him know you won't hurt his girls is hugely important! I also think you have to get through that inevitable "coming of age" stage as smoothly as possible. I raised a d'uccle from a couple days old and he was fine until he got to about 5 months, then started the posturing and biting when I came around. I started handling him more and more and I think we got through that and now he's much more relaxed around me and even likes to be held. You gotta start with something you can work with though, a mean roo is gonna be a mean roo. Good luck! Your babies are cute!
