Hi everyone. I just joined. I have had just a handful of chickens for a while. I just sent my husband to get some bags of sand for one of the rooms for the chicken coop. Bags are easier because it is real rainy here in Oregon. But, I'm afraid it could be dangerous to them. The brand on the bags is Sakrete, Multi-purpose sand. It says it can be used in pet areas. But, it also comes with a warning about breathing it in and having silica which is known to cause cancer. I don't want these hens getting poisoned, and I don't want their eggs to harm us. My husband says there is no chance that Sakret would sell something for animal use (including cat litter boxes) if it could give the chickens cancer. But, I told him the uses listed were for animals that don't eat the dirt like our chickens do! I'm afraid they will eat this silica and get sick. But, my husband said sand IS silica. I did a google search and didn't find anything. Can you tell me if this sand (that is also used for concrete) okay for my chickens? Thanks.
