Twin calves, two days old

We had to bring the cows up close to the house; Mama would take one calf along with her and forget about the other.  We'll turn them loose when the calves are strong and knowledgeable enough to stick together... probably a week at most.  I think she'll have plenty of milk, since there's Shorthorn in her background.  I'd love to raise one on the bottle, and keep it for a pet.  But it would be such a shame to seperate them.
