Alright, thank you. I guess I'll just have to watch and see how much the weigh compared to our white pekin and then I'll know which it is. Thank you, all of you.
Oh and as for the black/yellow duck. I was watching him last night and he wasn't standing up as straight like that. He'd switch back and forth but mostly stood like they other ducks we got (pekin and mallard). So I think he is definitely a black swedish. Thank you all very much for your help.
