Chick Poop Question!

[reils500]

I got six 4 week old chicks 2 days ago. They all are active and eating and appear healthy. This morning there were two poops with blood- does this look like normal intestinal lining she'd or is there something else I should be looking out for?
This was the best picture I could get...

It could be intestinal shedding, but if they were mine I would treat for Cocci to be on the safe side.

Dosage for Cocci is 1 1/2 teaspoons Corid powder per gallon or 2 teaspoons of 9.6% Corid liquid per gallon
Give for 5-7 days - make sure this is the ONLY water available during that time period. Mix a fresh batch at least once a day.
