Mystery chickens donated to us

[drmama]

Hi. Brand new to raising chickens, this is our first flock. The first week of May eggs were donated to my kid's classrooms to hatch them at school. We got 7 of the chickens. The farm that donated the eggs has dozens of breeds and had no info on the chicks.
We love ALL of them, but live in no rooster ordinance town. Could you help me figure out what I have & if they are roos or hens please?? One started crowing a little this morning, but stopped when I went out there so I don't know which.
Thank you!!

They all might be roosters.
The black one you too knew individual pics of is a roo. I think I see saddle feathers near the tail.
Can you get good side views of the other ones too?

I think they are about 14 weeks. Let me see if I can get better pics.

14 weeks then all 3 are cockerels.
