Sounds like coccidiosis to me.. the electrolytes may make things worse and/or should be discontinued during treatment with Corid, in case they also contain B vitamins.. since the Coccidia feed on thiamine.3 days ago we started the flock on save a chic electrolytes. This seemed to not help at all. Last night I started the flock on liquid corid with 3.75 mL in our 1.5 qt waterer thanks to yalls amazing answers to others questions concerning cocci. I didn't notice very much improvement this morning before work.
If she isn't drinking much she may need a dose directly to the beak.. a small drop just below the nostrils will roll around into the mouth (I hold the chick and use my finger bend to help catch the drip). Or encouragement by bringing the drink to her,
There are 9-11 strains of coccidia known to effect chickens.. the deadlier strains, like the one that shows up as blood in the stool would kill a chick off much faster simply from the blood loss. Many chicks survive, even without treatment simply by improved conditions IF their individual immune system is strong enough.
