It wouldnt hurt to move it right now.
Ive had staggered hatches where one chick was in the brooder for a day before the others. She also hatched day 20. All the others hatched at night on Day 21 or early morning Day 22.
As long as there is a source of heat and the brooder is warm enough the chick will be ok.
If no other eggs hatch you should try finding the chick a friend though
