Nine days ago I adopted 3 baby chicks from Meyers Hatchery via mail. I got an Easter egger, Olive egger and a lavender Orpington. They are the sweetest chicks. Yesterday I noticed 2 of them drop some foamy yellow poop. I was worried it might be coccidiosis but am finding conflicting info on the internet. All 3 girls are eating, drinking and are energetic. Does anyone have any idea what this could be? And, if I treat them with CORID and it’s not coccidiosis will the treatment hurt them? Thank you so much for your help.
