I feed my 8 week old chicks Dumor chicken grower/starter, which is a lot darker looking than the chick starter I had them on previously. They are 8 weeks and have already had a bought of coccidiosis with hamburger poop. I treated that with corid in the water for 2 weeks at the recommended dosages on this site.
Theu alternate this with normal looking poo and there is more normal looking poop than this kind. Is is regular cecal poop that is just dark due to the darker chicken feed??
