lol need to learn... We use PURPLE! We use the big Y Tex tags on the cows (both ears this year for my geekie record keeping ease :roll: )
We started using cow sized Z tags last year on the calves (they are not huge). We number them on the spot and we really like them. They don't tear out a calves ear the way a y tex calf tag will, and even though I really didn't like doing them at first (I was raised doing y tex button type) I like them now. We do like not having to mess with finding buttons now that we are earmarking, giving alpha 7, and tagging at birth. Also the dang black piece that goes in the y-tex tag at the top of the neck around the hole was forever falling out and the back won't stay in at all without it so we were digging around the tag box scurrying to get it in and ready before mama and baby took off.
We have looked into other colors but between our neighbors here and at our summer pasture, we are locked into the purple, which does show up decently against the black cows, and is pretty easy to read... Personally, I would choose Red with white lettering. Oh maybe not, when I had my own cows (before k_ranch and many other things) I had blue y tex with black lettering. That's what his dad uses now though... ok enough rambling :wink:
