Would everyone look at your local feed store and see if they have "Ren-O-Sal" tablets for chickens on their shelf? They stopped making it some time ago and I can't find it anymore. Maybe some of the older feedstores in your area will have some. It's OK if the date is expired. Doesn't matter if it has been inside. It comes in a small white bottle label REN-O-Sal. I would be happy to pay cost and shipping on it to get some for my babie chickens before I run out this year. Thank you. Just e-mail me on this site if you find some. (look on the back of the shelf in the dusty areas too).
