What else can I do for coccidiosis in my brooder?

[mirandalola]

Everyone keeps saying I've got the brooder too hot, but when I turn off the heat lamp (which I do twice a day so it can cool down enough for me to switch out the bulb - I also believe in a good night's sleep and I sleep better when they're not peeping all night so I give them a blacklight bulb at night) if I forget, and the lamp is off for more than 15 minutes or so, without fail there's at least one chick shivering where the lamp would be. I don't have a thermometer on the warm side but I've read repeatedly that the chicks' behavior is the best indicator of the right temperature, and they move from one side to the other, scratching and peeping contentedly.

This is my first time to have chickens, but I had parakeets when I was a kid and it is so much fun for me to hear those same happy little chuckling chirrups coming from my chickies as I used to hear coming from my parakeets. I know that sound, I know it means happy birds, and my chicks make that sound all day long, except when they're napping. They don't seem too hot at all!

Every time we've had the opportunity to try to save one of the dying chicks, their little feet were cool to the touch. We held them close to our bodies to try to warm them up, and it didn't take long for their little feet to warm up, but they still died. Would their feet be cool to the touch if they were overheated?

Also, my chicks are a mix of 8-day-olds and 2-week-olds. Most of them are 2 weeks old, all the deaths have occurred in the younger population.

Older birds are likely carriers. The younger birds are just now exhausting resistance carried over from mother via egg. Separate age groups and stop treating older birds if not affected.

8 day olds would still need to be pretty warm, two week olds a little cooler, but by your description it doesn't seem like their overheated at all. I think your main problem is the coccidiosis. Id continue the Corid with a five or seven day treatment and see how that goes. Hope you don't lose anymore!

I know that you have to keep their temperature by their age dropping 5 degrees every week.
Like I believe you start at 85, but not for sure.
Then it would go
First week- 85 degrees
Second week- 80 degrees
Third week- 75 degrees and so on, as a reference to go off of. But it might start at 90 degrees, I usually depend my starting temp based on the temperature of the outside weather around us, summer cooler and the light farther, winter warmer, the light stays closer. Hope this helps.

But I think you've got the heat part down.

You don't need to use a heat lamp to keep them warm. There are other ways that allow the chicks to self regulate without heating up the whole brooder. https://www.backyardchickens.com/t/956958/mama-heating-pad-in-the-brooder-picture-heavy-update
Feeling their feet will not give you an indication of their internal body temp.

The rule of thumb on supplemental heating needs breaks down when the chicks ability to thermoregulate is compromised by being sick. If the chicks are displaying signs indicating they are cold such as being fluffed up or cool feet then work in getting them warmer. During the aggressive phase of infection they will be loosing weight fast and have a greatly reduced ability to absorb nutrients they do ingest. Care must be taken not to overheat at the same time. I can have 5-week old chicks that require supplemental heating when very sick, especially when they they do not have healthy brood mates or momma to snuggle up to.

Oh hallelujah! I woke up this morning and did a head count and all 9 are still alive! Happily chirping and drinking their medicated water and eating their food!

Oh, what a wonderful update to wake up to this morning!!
