Clear photos of the birds in a natural, standing position taken in natural lighting will be more helpful in assessing their heritage. What I can see appears to be green/willow legs, which would indicate EE. Where were the birds purchased from? (this will also help in sorting out their breed) Also, the top bird appears to have some rather pink comb and wattle development going on, but photo is not clear, is that what you see when you look at it in person?
