I am VERY concerned to hear that your birds have been eating $2 seeds throughout their life. Do you think a human would be recieving the proper amount of nutrition just by eating bread? Birds need vitamins. They need veggies. They need variety in their diet.
I give my birds apple, seed mix, mellet sprey. Thats it. They dont like the apple. I have tryed to give them lettus and veggies and losta fruits but they dont like it.. it isnt my fault they dont like it, is it?
