Can I treat coccidiosis with toltrazuril and amprolium at the same time?

[Nikidust]

I'm in the middle of treating some 6 week old chicks with amprolium and ordered toltrazuril which came today. I've read that the toltrazuril is more effective, but we are on day 4 of corid. Is it ok to give the toltrazuril at the same time or do I need to finish corid first? I had initially intended to do 7 more days of corid at the reduced dose. The reason I'm being aggressive is that I just treated my flock with 5 days of corid about a month ago and now my favorite chick just started passing bloody cecal poops. I really don't want to lose her to cocci, but I also don't want to cause more harm by over medicating or drug interactions. I tried googling but couldn't find anything.
Thanks in advance!

Please post photos of the poop and chicks.

Is she acting off at all?

I would not give both at the same time. Choose one.

Stop the corid and switch to the toltrazuril right away.
