Really it sounds like you are doing just fine on your own. You have them set up good. You are keeping a close eye on them. You are treating them and getting them to eat. What more is there? Get Fed Ex certified is about it lol.
For imported babies you can sell the regular looking ones for the going price of baby normals. The really fancy ones that may be dinkers can be offered for a little more with the option of taking offers. Just be sure to state that they are in fact CH imports.
Just keep up what you are doing and keep them quarantined for awhile. Once they are all eating well and sho no signs of sickness, you can use them to establish some reputation and help others get some new blood.
I would get them eaing a little more than 3 times. Three times is only a couple weeks. You want to keep an eye on them for at the very least a month. Preferably 2.
