Yes, you did. Here it is:Nope I didn't say that either.
And here is where I referred to it:If a chicken is deficient in protein for example it doesn't mean they don't get any. It can equally mean they don't get enough to achieve their full growth potential for example.
Now you are saying they can show signs of deficiency (like not achieving full growth potential). Yes, I agree that is deficient.
So yes, you did say it.
