I thought you were saying a chicken could eat a diet that DOES NOT PROVIDE the right amount of amino acids, and can still show NO SIGNS of deficiency.
Well, yes I'm saying that as well because that is also true. In order to know whether a creature is deficient in any chemical one would need to take a blood sample much as one would with humans. Like humans, chickens can be deficient in certain chemicals and show no exterior signs of this.
Most of the UK was deficient in one chemical or another after WW2 but they lived, many into ripe old age.
Nope I didn't say that either.Now you are saying they can show signs of deficiency
If you want to argue with me then at least report or quote what I've said, not what you may think I meant.
