i bought some chicks about two weeks ago from a feed store, all but the bantams were sexed as pullets, but i have a feeling the light brahma we picked up may be a male. they are living with some slightly older chicks, who were unsexed, and i'm absolutely sure that there are males in that bunch. the light brahma is the most aggressive out of all of the ones we most recently got, and he/she is squabbling just a little bit with the bigger boys. is she just sticking up for herself, or could she possibly be a boy? are there any visual clues?
