Age estimate help (and maybe sexing)

[cstarkers]

Hi guys, I got these chicks 2 weeks ago today, and the guy said they were "1-2 weeks old" and wouldn't really eleaborate. Any ideas on age? The only place I can keep their brooder is in my kitchen, and as much as I love them, it isn't ideal, so I want to know when they can go out.

The Sussexes seem to be oldest, and then three of the Plymouth's, and then the back left Plymouth seems younger again.

Guesses on gender would also be very welcome, although I know it's pretty early. I'm thinking front right might be a cockrel, but I'm a rookieView attachment 2384770
