I'd just make sure you get them from a reputable breeder who is willing to mentor you. Start with their schedule- (unless it's just ridiculous somehow, like feeding a week old twice a day)
I don't sell many goats as bottle babies since I normally dam raise, but when I do I usually keep them for the first two weeks to make sure they are taking the bottle, disbudded, and started well. I highly encourage goat milk for at least the first four weeks, then a slow change if switching to cows milk or goat milk replacer. By two weeks they are usually on 3-4 bottles a day and not eating overnight. I only feed in the middle of the night the first 1-3 nights depending on the baby/timing of birth. A normal three day old gets a late bottle at 10/11pm right before I go to bed, and an "early" bottle before chores, usually around 7. I start all bottle babies (1 lb Nigerians or 9# Lamanchas) on Prichard nipples. I switch the larger breed goats to bigger lambar nipples around two weeks most of the time but the Nigerians wean off the Pritchards.
I'd consider a day old bottle baby to a goat experienced home- but as a smaller scale breeder I don't have any "need" to sell babies right away. Usually my bottle babies I sell are 3rd or 4th babies out of triplets and quads.
