I've been struggling with coccidia in my flock for about a month, and just wondering if there is something else I can do while treating my birds, and what I should buy to spray my yard with. I had a hen quickly perish a month ago, fecal revealed coccidia, and I was advised to treat my entire flock with Corid. I live in an area where it's impossible to find, so I immediately switched them to medicated feed, and after days of searching for Corid, I finally ordered some, and then I found some neomycin sulfate locally and used that in the water instead. In the days leading up to treatment I did find some bloody stools, but no one seemed ill. After 5 days on the antibiotics, all seemed well, no more bloody stools. Fast forward a couple of weeks, and my chicks who were newly outdoors also became affected, despite having been on medicated feed both before and during/after being outdoors, and being in an area that the rest of my flock rarely frequents. I didn't know they were sick until I found one of them dead -- it had appeared fine that morning. Suddenly everyone had bloody stools. Literally the next day, I was noticing bloody stools in my flock again. This time I used Baycox on all of them (3 days instead of 2, for good measure), and followed up with Germe-Zone (vitamins). Now one of the brooders (indoors) has bloody poops, again even though they are on medicated feed and no where near the chickens outdoors. The brooder is kept clean and there are only 5 of them in there. I must have inadvertently transferred it. The only unaffected brooder I have at this point is my "chick hospital," in a separate room, with chicks who are on tetracyline. I don't believe that is a sulfa based antibiotic, it's just an odd coincidence. I'm going a little bonkers. Yes, we've had unusually wet weather lately. I've been making sure that any sitting water in my yard gets covered in clay and DE to dry it up. My chickens are free range and have lots of room, so they're not all confined to one area or overcrowded. We do have a LOT (I mean a lot) of earthworms, and of course we have wild birds etc, hard to prevent all of that. I've never had a problem with coccidia before, not with birds or puppies or anything else. Is there anything I can buy that I can put on a hose attachment to spray my yard with (something that won't kill the grass or harm the bees etc) that will kill the cocci? I've been religiously cleaning out the coops and raking up poop from the yard. We are moving in a month, and I want to make sure I don't inadvertently bring a problem to my new property. Thanks in advance!
