Has anyone used this? I know Oxine is the cleaner of choice but it's out of stock nearly everywhere and not long term shelf stable (from what I've read) and I really don't need that much. The Vikron S comes in tablet form, sold on Amazon and likely my local feed store, so seems better for the small chicken user. It is approved for chickens but I did have a question. Do I need to rinse this after application? The information I have found says to rinse anything coming into contact with food/water... which is fine. But my coop doesn't do well with a full wash down... I've cleaned and removed as much debris from my coop as I can without using water... We did have some sort of unknown disease towards the end... we culled her and the remaining 4 hens are in the freezer waiting to be boiled all day. So, we're starting over from scratch. The coop will have sat empty at least a month by the time we get new hens. Hoping to sanitize this week, so empty for a couple of weeks after sanitization. The runs are all sand, we live on a giant pile of beach sand 3 hours from the beach! So, those are fine at least... Thanks for the input!
