Hi there, welcome to BYC!
I do think those are both cockerels. Two can often get along just fine, many of us even keep stag pens if they do pester the ladies too much.
Your Polish boy.. probably about 12+ weeks not quite 16.. Is he bearded? I wasn't able to make out his face.
The Red.. looks lighter than RIR.. to me. Maybe New Hampshire Red or Production Red?? I'm not sure.. like you said just having having fun with the gender/breed question game and always keep learning!
I know the subtleties will become more obvious with maturity and maybe easier to tell then.. just thinking sometimes things are mislabeled, mixed up, etc.
please allow plenty of time for maturity before deciding if one must go... ALL teenagers are awful.
But since hormones set in at different rates.. the more hormonal one may SEEM the most aggressive of the two.. BUT my perfect gentleman lap boy eventually became my ONLY rooster ever to attack me despite being an early favorite and good with the gals. Once his mating hormones kicked in he tried to pull hens out of my lap, stalked me, charged me, sneak attacked me, and crowed relentlessly when he saw me.
Since then though I have many a good and balanced boys that never looked at me with the stink eye.
You say one is smaller than the rest of the group.. is it bantam by chance?
Hope they all grow up and get along super well! Will you be able to consider using a flock raiser or grower full time and offering oyster shell on the side for your active layers when they start.. so your boys aren't getting excess calcium eating "layer" feed?
