Just got 16 chicks, not sure what kind or gender

[badbowtie]

A local guy that I bought chickens from last year, I called today to get a couple for my neighbor and he was telling me that he's got a mink that is killing all his chickens and had 16 chicks that are almost 4 weeks old that he told me that I needed to come get before they get killed. So, I went and picked them all up, just not sure how many are roosters or hens, or how to tell. I will split them with my neighbor, but not sure what to do with the roosters. Here are a couple of pics that I took.

They look like mixed breeds, possibly some Easter Eggers. As for genders, more time needs to pass.

Any idea at all what breeds he had?

I am not real sure he had about 50 2 weeks ago and they all free roam his yard so hard to tell. He did mention some were jersey giants I just hope all the chicks are not all roosters.

I am going to split these with my neighbor and I don't want to end up with all roosters I am not sure how long before we can tell which is which figured still have about two weeks before we can let them in the coops and runs.
