Need Advice! Chick down!

[Down by the Bay]

Last night when I checked on my brooding chicks one was down, it looked like it had been kind of stuck in a corner behind the waterer and used as a stepping stool for a bit. It was rather weak and cold, so I brought it inside and warmed it up under its own light and kept it in all night. This morning it is up and at em again, looking quite perky. Just wondering if I should put it back in with the others today or wait a bit?

If it was mine and it's acting normally again and back up to full power I would put it back with the other chicks but maybe try to make it so it can't get stuck again. Good luck with them all
