so iam tired of hunting all over for calves  to fill my feed lot barns no calves to be found. when I do find them they are pricey. I am thinking of  buying like 10-20 cows and dry lotting them in my feed lot pens. I have corn silage to feed them and straw. I know nothing about moma cows just looking to learn. where do I find them? what kind to buy? how old?  I have a friend that will let me use a bull. thanks in advanced   brandon
