The first pic, with the 2 cockerels are clearly crele, probably single barred, which are gorgeous in phenotype, but instable in genotype. The other 2 pics look like the MF leghorns I got some years ago from Sand Hill. They were not bad temperamentally, but I decided not to invest the time and effort trying to get them to where they should be. I am not an expert on the MF pattern and colors, so I decided to leave it to someone with more experience or at least enthusiasm.The neck definitely reminds me more of crele. But in person the white spots really do look like white spots rather than barring. But then I'm a newb who just likes pretty chickens so it works for me either way.
