No, buffs are orangey, that chick looks red in the pictures. Both are definate roos. Combs are way too big and red for a girl. I think you have a white leghorn and a rhode island red (rir) or new hampshire red (nhr).
Thank you. We have become attached to them... Our city does not allow roos. I'm crushed. They sing like girls? While they chip a lot, when alone, when we socialize with them, one of them sings. It does this bird type of singing thats really pretty. Gonna miss them.
Now you have a coop all ready for the spring when Tractor Supply (or the local feed store) gets in their sexed chicks!!! You might also be able to find older chicks or adults on CraigsList or the auctions here, too
