underweight 4 week old chicks?

Weigh the chick each morning to see if she is gaining weight.

If you are worried about coccidiosis I would follow these dosing amounts and treat with 1.5 teaspoon dose instead of 3/4 of a teaspoon.
Treating Coccidiosis with Corid, Amprol, AmproMed - The Correct Amprolium Dose

I almost started with that dose but because the signs were so subtle, I went with a “moderate” dosing. Would it hurt to increase it now? Or should I wait and see how they do at this dose? Again, it was one chick having diarrhea, the others didn’t. And some ruffled feathers. It started after I started introducing outside soil to them. That’s why I assumed it was Coccidiosis

The chick to the right of the circled chick. (I circled that one to see if others thought it’s might be a roo, and noticed the others feathers when I looked at the picture)
