Another coccidiosis related question

[1Crzychknlady]

Last weekend we began losing baby chicks to what I’m almost positive was coccidiosis. Bloody poop, lethargic chicks, standing and sleeping, standing alone in the corner etc. and even with treating with corid we lost a total of three (out of our 9) chicks. We lost one every morning for three mornings and I had the three that died separated from the rest in a different brooder because they were the only ones showing signs of being sick.
Fast forward to now. The remaining chicks finished the 7 days of Corid and are active and eating and drinking fine, but have a little bit of runny poo but maybe it could be to switching their feed to a medicated one or drinking a lot of water since our temps have been warm and drinking more water?
So, my question is what happens after this? I know some say to treat again after 2 weeks? Is there a reason to that? Should I put all the chicks (the young ones and older ones) on a preventive dose of corid in their water? The chicks are about 4/5 weeks old right now and we are wanting to begin the transition of putting them out with our other 8 week old chicks that are in the coop and introducing them. Should I put the older chicks on a preventive corid dose too if we decide to introduce them? I started the older ones on medicated feed when all this began last week but that’s it.
Any advice is welcome!
I guess I’m wanting to know when it’s safe to put them with our other older chicks and what precautions to take to ensure they all stay healthy. We were planning on putting them in a separate area of the coop’s run starting next weekend just during the days, where they are in each others presence but can’t get to one another.

I am not well educated on this stuff, but be careful introducing the groups! Make sure to watch them carefully as you introduce them. If you notice any of the older hens’ necks puffing up, remove the chicks immediately. That means they are getting upset or ready to fight. Sadly I dont know much about that disease but I hope your chickens stay alive! I am praying!!

Yes, use cord in the water for three to five days. Only Use the corid with chickens that are in need of medicine. Make sure to also keep a extra clean coop for the next few days, clean water and food as well.

Corid* not cord

I think it is safe to start introducing them whenever you want.

Coccidiosis is not something you every completely get rid of. It's everywhere. Chicks normally develop some immunity as they grow. They just need gradual exposure, rather than an overwhelming exposure (which is why you needed the Corid-- they had too many coccidiosis protozoa at once, and needed the medicine to knock the numbers down for a bit.)

You shouldn't have to worry much about spreading coccidiosis from one group to another at this stage, and you've already got the corid on hand in case you do need to treat again. Just keep an eye out for symptoms, and treat if needed.
