A couple of years ago I raised a twin heifer by bootle. She was the first born and ended up laying in an inch or two of standing water. So she got cold and couldn't stand, nothing a few hours on a blanket next to the wood stove didn't fix. She spent her first night on the front porch, the next morning she was standing in the middle of the yard ... So to the barn. Even with her chilly birth she needed no anti biotics. In your case only thing I would watch right away is shipping sickness, may need a dose of LA200. I had never raised a bottle baby so figured what the heck, but the two main things I did different were I never put her on a bucket, stayed with a bottle until I weaned her at about 5 and 1/2 months, I stayed witha bottle to avoid milk belly and it worked great. Second thing I did decided to feed more milk as she got older, by about three months she was on two bottles twice a day plus calf starter and free choice hay. She and her twin are well bred cattle so I wanted to see if I could have her wean out as heavy as her naturally raised twin. She was a little lighter and slightly small so I was glad I gave her the extra milk. Now I was raising a replacment heifer were your raising a steer (?), also I was experimenting a bit. You may not want to add the extra expense of extra feed.
The two things I learned from the experience; extra feed and staying with a bottle worked well for me. Second, I hope I never have to raise another bottle baby, lots of extra work and expense.
