Thank you,micok and jack,I learn a lot.I know feed peanuts has benefits,but i do not know there are so many benefits.
but I think feed peanut should be proper.If the breeder is fed to many peanuts,especially the hen will be to fat and can't lay eggs any more. if the racer is fed to many peanuts it will be obesity,and it'll cost him more and energe back home.So i think should be cautious.
