Sex please

Hi!
I am wondering if anyone can sex the two chicks circled for me please? I'm thinking hens.
the other four are females I know but these two I bought as straight runs.
thanks in advance!

It's too early to tell with these. How old are they right now, and what breed(s)? Also, better pics of the heads would be helpful for when you post again in a couple of weeks.
