Howdy chicken8
I still marvel at all the differences of opinions and how we are able to share them here on BYC.
I have read that chicks should not be wormed until at least 12 to 14 weeks of age and also read the complete opposite:

A possibility could be Coccidosis; definitely keep an eye on her poop. Blood is a sign of severe cocci but it is possible that she has it, even without blood in the poop. She is about the right age.
The Learning Centre has a great article on Coccidosis:

Also, check her out for Mites or Lice:

This is a good poop chart, definitely one to bookmark:

I hope you are able to find out what ails her.
With regards ACV; it definitely is not a wormer but I use it and was told about it by a friend who has had chickens for a very long time and some of the reasons he uses it are:
* It apparently maintains a good pH balance in their digestive system and makes it a little uncomfortable for worms to live in. So while not an actual wormer, it can be a deterrent.
* It can act as an antiseptic, killing bacteria in their throat and is reported to keep bacteria out of their water. I know it is recommended to people with sinus issues also.
* Some think it increases egg production but I can't comment on that because I only have bantams who spend more time broody than they do laying
Different strokes for different folks and the above is just my opinion.
