Hello fellow chicken lovers i have some questions about coccidiasis because i suspect my hens live around it unprotected, i lost one 7 days ago and right now i have another sick hen. My experience with chicken diseases is limited and i am trying to understand if: 1) if i give coccidiasis medication to the rest of my flock to keep them healthy, does that mean they will never get infected, or do i have to give them again after some months? 2) If a chicken is not eating, feeling sleepy and finally cannot stand to its feet because of loss of power and weigth and has yellow liquid poop, but with no other signs of disease, chances are its coccidiasis? Please try to answer those questions, i want to help that dying hen and most of all i want to help my flock, i have no trustworthy people with chickens that i could ask and learn anything at all. The only pet shop was out of meds and gave me an EXPIRED(6months) coccidiasis medicine for free that i DID gave to the dying hen because i wanted to skip the "cull option". They will bring not-expired medicine next week but its very expensive. Do you people give coccidiasis medication to your flock to prevent the disease? The only reason i believe its coccidiasis is videos i have seen, i am lost here. Is there a list with drugs that the flock needs to take as precaution?
