I'm not an expert/scientist on feeding/nutrition but... Do we REALLY need them? I mean yeah, it is convienet, and good for the people who just want animals, and have no desire to free range of feed natural foods and such, just open a bag and feed, no questions asked...not downing that person by any means, just explaining my point. I want to start "serving" my own whole grain and foods. I went to my feed store and asked the owner who is a vet tech and animal nutrition teacher, what kind of separate whole grains she had. She asked me what for, I didnt want to tell her because I didnt what to get the third degree of how bad that is blah blah. She said that at the grain company, they have scientist who fallow a chart that formulates what they need and they put it into a pellet. She was going on about all this scientific stuff. "If you give to much of this, it could be fatal, they may not get this, or this, ect, ect..." But really...??? What does a true free range chicken or wild bird eat?? Grains, grasses, weeds, sprouts, berries, bugs. They get their nutrition, vitamins, minerals and trace minerals through all of that. And while if you give a chicken nothing but say grain, or nothing but bugs/protien source, they may get a vitamin overdose and a deficiency. But if you give them everything, and enough of it, a choice, I really believe they will eat what they need at that given time. I believe nature made it so they know what they need and will seek it out by natural choice. I want to do an experiment. I want to give them free choice of foods. I dont want to measure. I want them to eat what they want, when they want. While they free range, they may not be getting everything, so I need to give them what they dont get. I cant really do this until I have a good supply of bugs and a good protein source. I want to do worms, I think would be the easiest non timid way. I need to focus on my compost and a way to encourage a good bug population. Any suggestions??? What do you think about all this?? Anyone agree with me? Thanks for listening.
