4-5 weeks old, little ladies or gentlemen?

[ChickysInHawaii]

I’m wondering about two of my 4-5 week old chicks who are behaving a bit like Roos. We are in Hawaii and have lots of feral chickens so these are two orphans who were rescued separately but are no more than a couple days apart in age. The first photos are of Lilly, who differs from the standard feral breed and is quite hefty. The last photos are of chicky who is a traditional feral Hawaii chick.

Please let me know if you think these sweet babies are girls or boys and if you have any idea what breed Lilly (1st pictured) may be. Thank you!

There is nothing overtly "cockerel" about either of them. The first one likely has a little Brahma in her.
