I recently ordered a 50 lb. bag of Oxbow pellets, and I also added a bag of Timothy hay since I was having something already shipped to my house anyway and the local co-op hasn't had Timothy in ages. For some reason, this bag has way more brown hay mixed in than usual. In fact, I've never had Oxbow hay that wasn't mostly green, but if you didn't know better, you'd swear I had bought a bag of Kaytee Timothy hay. Do you think I just ended up with an older bag?
