Is it normal for her to poop like this or should I medicate her?
Welcome to BYC. No blood in the stool is not normal. Occasionally all chickens can pass some orangey-red intestinal lining, but blood normally is from coccidiosis in 5 week old chicks. Amprollium the ingredient in Corid, Coxoid, Amprol, and probably other brand names, is the best treatment. We can help with dosage if you name the brand. Sulfa antibiotics such as Sulmet (sulfamethazine) and sulfadimethoxine are also used as well as other medicines as toltrazuril, depending on the country.
