It will be much better off with a few more chicks. You may be able to find a few at one of your farm stores. You can also post your need to local FB poultry groups to see is someone has a recent hatch and could sell you some chicks.
In the meantime you can get a feather duster and a mirror to keep in the brooder with your lone chick so it doesn't feel quite so alone. I might go as far as to play chick noises for it too.
