I have 2 pairs, when I bought them the breeder told me to use laying crumbles basicaly chickens feed, wich i already had, but he said I can use bird seed, what kind of bird seed is he talking about? Should o mix it in with their food or put it in seperate dish? What kind of treats do they like best? I hve been giving them dry meal worms & millets, and both pairs have cuttle bone, Thanks
