I was adopting a calf on last year and the cow didn't seem to take to the adopted calf. I stood in that pen twice a day every day for what seemed ages. So when it came to letting out time I thought right, he will probably get stuck in elsewhere and if all fails he will just have to come back in. So off down the field they went. Looked at them that night and stood there in the middle of the field was said cow and adopted calf drinking away like a good'un!!!!
