These are my daughters new pets as I'm allergic to anything with fur. We have 3 chicks one week old. At least 2 are having watery stool....but this morning one of them had blood....bright red...in it. I understand it's most likely cocci with blood, but my chicks have not been around any others (My sis got 40 chicks hatched 2 days before, we picked out 3 of them, and none of hers are sick), they haven't been outside and they are on medicated feed. Is this still possible it is cocci? My daughter is worried so any help is much appreciated.
