Title says it all. Do you mix your own or buy it from the feed store? This is a place where we can compare. I buy mine from the feed store. I forgot the names of the seeds in it, but they are very common in birdseed, etc. I also find the occasional stalk of some kind of plant, but very rarely and my chickens eat it anyway. As you can see, mine contains cracked corn, the small round seeds common in birdseed, rat/mouse food, etc. and also the flat oval seeds.
