Thats why they did what they did
Why didn’t someone take the calf and bottle feed it until it was old enough to eat on its own?
I raised a piglet on a bottle and several calves too. It’s not that difficult.
I once found a tiny kitten that had been rejected by its mother. I carried him home in the palm of my hand. When we took him to the vet for his first checkup, the doctor said he wasn’t even going to vaccinate him because he wouldn’t live. Bad heart. He made it to about 10 months, then vapor locked and keeled over.
