If she's acting tired, then I'd watch to make sure she's drinking and eating well.
A direct dose of Poultry Nutri-Drench for a couple of days wouldn't hurt.
Time will tell if she'll be o.k. or not.
Get her through the shock. Keep her warm and give her tiny sips of warmed sugar water or gatorade.
Do make sure she's got room to move away from the heat lamp.
She may enjoy being left to be quiet, to sleep and be settled down for a few hours...
