Bought a heifer from a friend. Heifer was on grass with mother up until he delivered her to me and has never seen feed. By the time I wean my calves they are already eating feed because I feed the cows a little every day so I have not had this happen. Tried to feed this heifer but she has not touched the feed yet. How long does it normally take for a calf to figure out what feed is? I have her in with a smaller weaned bottle calf that belongs to my neighbors. The smaller calf is eating feed but not much. They have some grass but I want them eating feed good so that I can move them to a larger pasture and be able to get them up easier if I need to. Any suggestions?
