Has anyone used either or both? I've used dumor on my flock almost exclusively since march since it's what tsc supplies. I got a bag of Seminole to feed them a few weeks ago at a closer feed store. I figured if they liked it the same and all went well I could save myself a drive. But since eating the Seminole they have mustard toned poop more frequently! I'm going to go back to dumor since I'm almost out of feed today. Anyone else share the same experience or are my birds just odd?
