They are EE's. Muffs and green legs tell the tale on that one. As far as coloration looking like a delaware or brahma, perhaps one of those was in these chicks lineage since EE's are "mutts". ( not my favorite word mind you) They are mixes that can carry the blue egg gene. Yours very well may lay blue, green or maybe just brown depending on whether or not it has the gene. I had/have two EE's. Their mom was a ccl and dad was a black orp roo. One chick is solid black and lays a pale brown egg. Her sister (RIP) was solid brown and laid the most lovely green egg. Both have/had a ccl comb.
