So... I bought a straight run of australorpes....

Since I wasn't expecting barred rock, (I think)? I am not sure if this is a roo or pullet. All chicks are just under 8 weeks.
There are 2 barred rock. Look the same to me. Both a little bigger than my australorpes and leaders of the pack.

Any thoughts on genders? Any confirmation on breed? Any tips on keeping them together, or not?

Looks like in my opinion you have two males of the barred (probably Plymouth rocks), and it also looks like one of your australorps is a boy :'(

Both of the barred ones are roos

Both barred ones are cockerels, and it looks like you have at least 2 australorp cockerels.

I actually have 4 australorpe cockrels, which is fine, but I was kinda hoping the barred rock were pullets, because then I think the next generation would have been sex link, if I have an australorpe male and barred rock female. Aw well.
