I bought some alfalfa from the feed store today to put in the outdoor area for my chickens. I was told that chickens like to dig around in it and it would alleviate some of their bordom, but after I set it out there I was wondering if it could have mites that would infest my chickens. Does anyone know if that is very common? I am just wondering if I should take it out? I don’t want my chickens to get any kind of mites!
