I use Saturday Lime supposed to be safe for chickensI am so glad for BYC and for those of you who give advice to a newbie chicken tender like myself. I have been having a big problem with mold in my chicken pen. I thought it was from the drainage issue from my neighbor’s property (which DEFINITELY hasn’t helped). But I also realized that it’s probably because I also spread some of the feed on the ground with their scratch. I am going to try to get the lime and see if it works… as long as it doesn’t hurt my chickens to have direct contact with it.
