For the first few days - 3-5 - I would give them Nutrical two or three times a day. This just gives them a little boost for right now. They are definitely warming up but this is still a total shock to their system. You have to be able to anticipate their needs right now. This is the time when most of the orphans are lost. The shock to their system is not handled and they start to fade. Just remember, you cannot give them too much good stuff. Oh, and make sure that they have access to fresh water. They won't really know what it is right now, but they will quickly figure it out.
