Breed help please!

[We-love-chickens]

Hi there, we are still relatively new to hatching chicks and we've had a few hatch so was wondering if anyone could help with the breeds of a few of these. I am pretty certain I know the breed of a few of these but if anyone can shed some light also that would be amazing. Thank you in advance.

I the larger pics of the white bird a parent or just an older chick?

Do you know anything about the parent stock that might help narrow things down?

Did you get them from a hatchery? First one looks like leghorn cockerel.

Hi they are all the same age. Some just seem to be growing at an alarming rate the white ones all seem to be double the size of the smaller ones.
