First one I am going to say a cross. It doesn't seem to have single comb that I cochin should have, I could be wrong. Cant see it very well in the picture. I am going to guess Silver Seabright on the second one. 3 could be a delaware but I was thinking maybe a columbian wyandotte, dont know though. And the last one is a buff laced polish, that one I am certain of. Others are just a guess.. Good luck!
