We just stopped bottle feeding ours. She was born 2/10. We did not use formula. She was raised on whole cows milk from the grocery store. She did fine the whole time.
Was going to post a similar question. Three months is a good time to wean a bottle calf? I know Murray(My calf) is an avid grazer when I take him out on halter and has good quality hay(Clover/Fescue) He eats a 1.5lb coffee can of his starter/sweet feed/corn in about 2-3 days. Just hope that's enough. Was told that I may have to bottle feed him for 7 months
