Yep, that's a hen for sure. Here's a pic of my roo and he's only three months old ... and definitely crows 
A LOT!!! Since I'm new to this thread I was wondering if the crowing is a breed thing? My other bantam roos don't hardly crow at all and this guy is noisy all the time and kind of fiesty, ie he doesn't want to sit still at all or to be held but he doesn't attack other birds or anything.
 
Usually its the dominant roos that crow the most. I have 5 roosters and only 2 crow all the time. When I had added a Polish roo to the bunch they got along well and he crowed a few times a day for the first couple weeks and now he doesnt crow at all

.....wonder how you make a rooster crow more???
 haha usually its the other way around but I love hearing roosters crow
