I've only ever gotten Aseel hens. I've currently got one, but had two a while back. These hens are extremely tough, so I don't have to worry so much about things getting into the coop, but that also means that I need to be careful.
My current Aseel hen goes broody fairly frequently, and she doesn't take kindly to interference. I have to catch her off the nest to see how the eggs are doing, because the last time I messed with her, she managed to draw blood (not much, but some). She is a determined broody, and doesn't switch nests like all my other birds, but I haven't gotten chicks out of her yet, so I don't know how she does with chicks (she's gone broody twice so far, and last time didn't go very well, but it was probably my fault.)
Aseels are extremely intelligent, in my experience, as my hen knows how to do some damage when she feels she needs to, and will twist her head away when she pecks, trying to tear the skin. She has also managed to peck my hand when I tried to distract her with a piece of straw (I wanted to candle her eggs). I waved the straw in front of her head, and she attacked the hand holding the straw instead. I see her intelligence as a mixed blessing. On the one hand, I can't really mess with her, but on the other hand, she should be able to keep some of my other birds safe, and, hopefully, her chicks.
I've always had a mixed relationship with my Aseels, as I love their broody/protective nature, but I wish they'd be a bit more sociable...
