New chick is drinking plenty, but not sure about eating

[Karen12]

I just got my bantams in today and all made it alive! I do have one who drinks plenty but seems to sleep more than eat. I mean, she does eat a little...but not neatly the quantity as the others. I have save-a-chick in the water now and I am planning on doing a day of ACV tomorrow. I tried watering down some of the feed for her, but she wasn't a fan of eating it. She is asleep quite a bit, but she did one charge across the brooder and promptly fell asleep. Sould I be worried? Or is this just first day home tiredness?

The others are currently chasing each other around with a shaving (tag) but she could care less about them running like mad. Any advice would be greatly appreciated

Forgot to add, she is by far NOT the smallest chick in the batch. She almost seems just a little "spacey". Her poop is mostly liquid with a very small amount of solid in the center. They were hatched in Monday.
