Thank you, I did not know about poultry vitamins, so I put aviary vitamins I gave my budgies in their water. Iron in vitamins? That is not good for chicks? I will have to look at the label. I have been coming to the opinion as of late that for people and the like, to many supplements are superfluous or even harmful. A good diet is best. Stress is the most harmful, it has taken its tole on me, I can imagine what it dose to animals. The body has a hard time, I wonder if this is when supplement need to be given because it seems stress keeps the body from working the way it was designed. Adding in that foods just are not as rich in nutrition to day do to a combination of facts, not just depletion of soil. I am beginning to wonder if adding nitrogen to the soil is sufficient, it helps plants go, but dose it give plants what they need to help us grow. Maybe the old fertilizers are better for us, helping the plant grow is second. Dose anyone know if there has been a study on this?
