Hi all! I had a flock of 18 for 11 years that were kept in a coop using premium play sand. Most died of old age and I would still have 4 if not for a predator attack. I live in Fort Worth Texas so mostly hot and dry weather. I never had an issue with the sand and health. I just got 9 new babies so I am brushing up on raising them. I see all kinds of folks saying play sand is a huge no no but I never had issues. I still have a pallet of sand that I was about to dump in the freshly cleaned and repainted coop. From the veterans/experts out there….what are the issues you see using this again?
