I got myself 4 baby chicks 4 days ago. I don't know their age, most likely (were) 3-4 days old. One chick was sick, always sleepy, got regularly detached from the group and stood alone, from the very beginning. I gave it a mixture of half-boiled egg and sugar and sugar-water (advice got from this community), to this day the chick doing better although not fully recovered. Problem is : another chick who was kind of the leader of the group, was very active, showing the same symptoms. I think it's Coccidiosis, I'm mixing garlic with their water supply everytime, tried sugar water, but the newly affected chick seems to be not responding to these endeavors. Has anyone had similar situation or can an experienced person give some valuable advice.
