What breed are these? My pics don't really show their tails very well -- their tails fan out in a triangle from the back but only when they want to fan them. From the side their tails fan out much wider than they look here and the tails stand very upright. They lay small white eggs (banty sized) and one lays blue eggs. Their feathers are glossy black, and they are smallish -- perhaps banties? They were fierce broody henmoms which now makes me think they are banties. Some have slight feathering of the legs which makes me think they are crosses of something. Any ideas?
