Keep an eye on her as she may need coconut oil again. I would just give her 1/4 tsp again to be on the safe side.
Make sure she is drinking lots of water. You can also make a mash out of the chicks feed. They do make a bit of a mess in it but it ensures she's getting fluid. I would break it up...
She may be constipated.
I would give her about 1/2 tsp of chilled coconut oil. You can break it off in little pieces and put it in her beak to swallow.
I would avoid getting a 1 week old chick wet as she could quickly become chilled.
