Feathering question

[wvhomesteader]

We have 11 chicks that hatched on April 20.
The Rhode Island Reds already have a good start on wing and tail feathers but their Black Australorp cousins aren't feathering at the same rate.

Is this simply a breed difference?
I've not had BA's before and was curious. They're all active and healthy so I don't think there is any cause for concern health wise.

The BA's also prefer to be a little cooler. The brooder temp is 85 and the RIRs like the heat but the BA's shy away a bit.

I can't speak to the other breed, but my RIRs all feathered differently, particularly the male. He had no feathers on his butt/tail for the longest time. And the girls all kind of came in on their own schedule, too. Our EEs also feathered on a sliding scale, so I'd say it's probably normal.

Thanks @ABard

I haven't had this kind and was curious.
I've got 6 layers and they're a mixed flock.
3 buff orpingtons, a sexlink and something else.
