Are my chicks dying of coccidiosis, salmonella, or something else?

He asked if there had been mice around the chickens, and I mentioned we have actually had trouble lately with mice in the house.

Did you put out mice/rat poison?

Could the chicks have caught salmonella from mouse droppings?

Yes, Salmonella are among the many pathogens transmitted by mice, rats etc.

Please post some photos of the chicks and the poop.

Hi all, thanks for your responses. Yes, I'm in Australia & it is winter here. We have them in a warm bathroom. I got them from a pretty dodgy pet shop & was told the two breeds I got were Isa browns & Australorps. However I suspect the two active ones might actually be something else? Theor wing feathers are darker brown. I'll try get better pics this afternoon.
Here's a private link to a youtube video if you wanna see.

The two that are sitting/wobbling have now died.
The other one with larger whitish wings probably won't make it by the time i get home this afternoon .
Leaving only two remaining.
I didn't get many pics of the poo sorry. Here's a photo of the bright red runny poo. There are some woodchips stuck there because i previously had them on woodchips before the towel.

I am very sorry. The only way to find out what caused their death would be to have a necropsy. Send them in to your state vet lab, so you will know what you are dealing with.

I suspect they were already infected with whatever is killing them now, before you brought them home.

Thanks so much everyone. Wow what a shitty few days haha. Just one chick dying after the next. The last two remaining chicks are still totally healthy and active. I've given the cocci treatment following instructions. Their poops stayed healthy looking the whole time too. I think they're a different breed. They seem a few days younger than the rest and didn't seem to get infected at all with this sickness, leading me to suspect that whoever supplied them just mixed in a few batches of whatever chicks they had. I think that batch must have been carrying/immune to the illness.
I'm hoping it was coccidiosis and not salmonella, because i think if it was salmonella then they will continue to be carriers even when healthy adults.
I will try look into getting a necropsy done. Not sure if I can find someone to do it for cheap/free. Don't have heaps of $$$.
Thanks again
