Ok, so I think the Delaware Roo is darn easy to figure out. My two other solid yellow chicks have since gotten splotches of brown on their feathers (so the consensus is that they're Red Sex Link males) but these two birds are still solid white with no markings. They are significantly larger than my Brown Leghorns (and not as flighty) so I'm thinking they're not White Leghorns. McMurray is where they're from... Could they be female Delawares? Or is that just wishful thinking and they're just two more boys to add to my flock of straight-run mostly Roos!!!
