Sick chicken- treating for coccidiosis but need advice

Last Friday I got two 8-10 week old pullets (BO and SS) and by Sunday I saw one bloody poop. Yesterday my SS was all fluffed up in the corner of the coop and I was able to start treating with Corid in the water (powder, as that's all I could get). These two are still kept separate from the other chickens but I'm treating everyone since they are in the same yard.
Today the poop is far less bloody, but I'm not sure if this is the sick one improving or the other one coming down sick. I don't know how long this stuff takes to work (if it's going to). My BO still appears fine, but the SS is still fluffed up and looks no better from yesterday, granted it hasn't even been 24 hours since starting Corid. I am not even sure if my sick one is eating/drinking at this point. She would still be pooping blood, right? The two are so close that I fear that separating them so I can monitor one's intake (the other one is definitely still eating/drinking) might do more harm than good. At what point should I start seeing a turnaround in the sick one (assuming she does get better)?

I have read mixed things about bringing sick chickens indoors and worry that it might be too cold for her- highs here are in the 50s and lows in the 30s-40s. Can she get better without me bringing her inside? If I do, I'd have to bring them both in to keep them together and then harden them off when they go back out- I have no idea how to do that as I've never provided supplemental heat.
Any extra tips? Just wondering if there's anything else I can do to make sure my sick one is getting the medicine in her and to help her get better.

Corid generally works very well. I usually see some improvement after about 48 hours.
If you aren't sure she is drinking her water you can use a syringe (no needle) or eye dropper and drizzle it into her beak slowly. Just don't squirt it into her lungs. It's not hard to do. Once she starts feeling better she should start drinking again on her own. Make sure you treat for the full 5 days. Its a pretty safe medication, and I'd treat everybody that was exposed.
As for temperature, you have to be the judge. If they seem cold, then I'd use a heat lamp, make sure she can move in and out of the warmth as she needs. If they are fully feathered, they are probably OK, but sometimes sick birds can get hypothermic.

@sabrina514 , you can make an oral drench for your sickest one by mixing 1/2 teaspoon water with 10ml (2 teaspoons) water, stir well and give 0.074ml per 100 grams orally Okay to do this once a day for 1-3 days even with the medicated water.

Your medicated water needs to be made with 1.5 teaspoons per gallon for 5 days, then 1/3 teaspoon for for 7-14 days.

Is that supposed to be 1/2 tsp corid liquid per 10mL? I don't have any liquid as it's not available in my area and I can't get it shipped here fast enough. Or is this medicated water mixed with water? I'm confused on how exactly to do the oral drench. I'm new at this, only had chickens for a couple months and this is my first experience with illness.
I was able to observe them long enough to figure out the other one is having bloody stool though nowhere near as bad- I'm hoping that she will recover. My sick one does not appear to be eating or drinking, is crying out and straining to produce stools that are basically small amounts of blood.

It's 1/2 tsp of corid powder mixed with 10 ml of water.
Dose for the bird is .074 ml of that per 100 grams of weight of the bird.
You give that once a day for up to three days in addition to the medicated water.

Keep your sickest ones in a warm room and worry about integrating them later. Cold will kill them.

Thank you for all the help- fingers crossed it works. I already brought my sickest one in and was able to slowly drip about 1.5ml of the medicated water into her with a syringe held next to her beak. I might go get my other too- so far she's had a bit of blood, but her stools are already looking more normal (still a bit of blood, but not loose) and she's been acting normal. I will try all these suggestions with my very sick one. Thanks again, so much for all your help <3

I did successfully get a dose of the oral drench down her. As long as she is not drinking independently, any advice on how much fluid I should try to get in her per day? While she will not take water on her own, she is willing to accept the medicated water (1.5 tsp per gallon solution) via syringe.
