The middle hen will lay well, prob light brown eggs, I don't think you're going to get any eggs from the guy in the bottom pic...prob not the top pic either...but would like to see the whole head.
the first one is a silver spangled hamburg. these were the original commercial egg layers in europe. good layers. the one on the right looks like game and the one on the left, i think is afemale of the species on the right so would rather sit than lay
