Yeah the wyandotte are easy and the two bbsplash cochins are also..
The darker one pictured alone kinds has wyandotte markings but is darker then the others.. the yellow one looks to have darker feathers on its wings.. goi g to try to get a pic of that
I'm assuming the white chick is the only other clean-legged one? It looks to be a Columbian Wyandotte, assuming clean legs. That would likely make it the meal maker
