If it were me, and my nurse-cow wasn't available, I'd try to get it to take a bottle. It would certainly take quite a few tries to transition the calf from teat to bottle. I would also get it started on feed.
I had 2 calves that I acquired that were a month old when I got them. Both at the same time, straight off the cow (story for another time). #20 took to the bottle as if she'd been on it since birth, #31 well, lets just say it was a rodeo. What I did with them was I put them up in a small pen with a run-in shed. I'd close them up in the run-in then catch the little buggers and shove the bottle in their mouth. Like I said, #20 took to it right away, but #31 took about 4 days of trying before she would come to me for the bottle. The feed I put in a wall mounted feeder, and they eventually got curious enough and tried it and started eating it well along with hay.
It can be done. Good luck.
