If there is too little of something then diluting it will making it a lot worse. Have you researched what quails need in there diet? Have you research what bad nutrition in animals can do? It is quit interesting what is needed and what will cause problems over 5 generation down the line. This is for quails not chickens I don’t think many people had quails that long ago but I have not researched that so I don’t know. yes the animals can probably live on random grains but that would probably not be the best, I am not saying pellets are better if you spend the time to make a good feed for the quails then it probably would be better then pellets but that will be very difficult and expensive so for many people it is not the best option.
a lot of grains and seeds are quite expensive in the UK compared to other places.
Please don’t take this the wrong way those are genuine questions this is not suppose to be rude at all, I don’t think I am over exaggerating. I agree people seem to think pellet food is perfect and there is no way anything could be better which is wrong.
