The Omega Ultra Egg is easy to use. You just measure out the right amount (instructions right on the bag) and sprinkle it over the feed. The chickens love the taste of it. I had no problem getting them to eat it. Their feathers are nice and glossy, their combs are bright red. Their egg yolks are a brilliant orange. I also think the egg color themselves have gotten deeper and richer due to the Omega Ultra Egg in their diet. The blues are bluer, the browns a deeper brown and the creams creamier. I also notice that their shells are appreciably thicker. I even dropped an egg in the run the other day and it actually bounced!
