Your Brahma looks a lot like my Easter Egger who may or may not be a boy!
I would think that you'd be able to keep him/her if you're moving soon. And no crow has to be a good sign. My boy/girl is 16 weeks old but has started a few rooster traits and has long curved tail feathers. Until I hear a crow I hold out a wee bit of hope that he's a she.
We have a racoon that wanders through our backyard but the chicken pen is *very* secure so we've had no troubles so far.
I live in an unicorporated area too - there's no laws against roosters - just noise! So I can keep him if no one complains.
