i bought a cow at the stockyards and it has had a calf that is very small. iwatck the calf suck and it seems as if it is getting very little milk. calf is not growing at all. thinking of selling the mamma and raising the calf on a bottle. the calf is a month old how hard would it be to get the calf to take a bottle or bucket and how good would he be able to make the change.
