At a poultry class at MSU last week, we learned a trick for making rainbow egg yolks. Because the yolk is made by the hen in layers, you can feed her a gel cap of paste food coloringblue, red, green, whatever for a week; then every other day switch colors. You should get colors laid down in the yolk in the order you fed the food coloring. They said you could put coloring in the feed, but it doesn't work as well.
Anyone ever try this? I don't think I'm going to go to the trouble (sounds messy!) but it's an interesting idea.
