I am going against the grain here, and saying they all look pretty girly to me. The saddle feathers on the light brahma are too rounded by half and the colouring is right - girl. The buff brahma - is that it on the second pic, turned away? - Definately girl. The cochin is a bad black, no blue, and is probably going to turn out to be a boy, but too early to tell. The second pic of the Easter Egger - no clue, but leaning towards boy with his carriage and hackles.
