Interesting that the feed in Europe is usually lower in protein than in America. That it's not optimized for herritage/ornamental breeds, do you see that as a negative thing? Because I wonder what they would need extra or less. Or does it have more to do with the economic aspect, that people are willing to buy more expensive (better?) feed for them than the production-oriented industry?
As for the calcium, why is this so high. Is this because it has advantages for the industry or because of cheap ingredients?
I find food very interesting, especially because I have some problems with one of our ducks that are probably food related. It seems as if he has a low blood sugar very quickly which makes him literally collapse and paralyzed for a while (we suspect this as it has happened four times now under different circumstances but always before feeding). Maybe this is a certain genetic abnormality, but maybe we can help him with better nutrition.
We want to buy chickens soon and I want to give them good food. I may want to put together my own food as I think if the proportions are right it is healthier for them.
