Right has a bigger poof on the head, has little black wattles. Left has no wattles and a smaller poof and is less feathered out. Same age. They're around... 12 weeks old, I think?
Another shot of the white one. I see no streamers but I'm not really experienced with silkies! The wattle is what's getting me thinking it's male...
Dark brahma as far as I know... might be hard to tell with how my son is holding it, but boy or girl? Same age, about 12 weeks.
