I see some messy coloring underneath the rooster's hackle feathers. Not clear, but I think he's the source of the barring. But if that's the case, shouldn't he pass that gene to all his chicks? No sign of barring on the black or the red.
I am definitely leaning cockerel on the red. Normally the white floof at the top of the wing has gone away by this age.
Pullet for the light gray. Black no indication one way or the other but I think pullet.
Barred chick I still thin
I can't tell if the rooster is single barred or not barred at all?
Is he the only rooster/cockerel?
(Also pardon I'm distracted, that bantam in the flock is super itty bitty compared to the larger birds)
So. I'm not seeing any noticeably barred/cuckoo birds in the flock picture. But somebody had to contribute barring to that barred chick.
If the mother is barred, (*and if rooster isn't barred) then that chick is a cockerel. That would be a sex-link (barred mom x non-barred dad = all sons single barred, all daughters not barred)
If the rooster is barred though, could be a pullet.
I'm not sure with the solid black chick. Could go either way.
The other two, I'm leaning cockerel but could be wrong.
The red chick, the wings have a patch of darker red coming in. Maybe it's just a change in color, or maybe it's splotchy red. Also, the comb appears to be going pink, but maybe that's just the lighting and picture
The final chick, either it's just how the pattern is coming in, but it almost looks like it has splotchy red markings coming in. So that's why I'm leaning cockerel.
also yes he is the only rooster in the flock
