I don't like coloring chicks becuase it makes them look like toys and most of them end up dead in a few weeks. You can color chicks by injecting the embroy and covering it with wax till the egg hatches. I don't know the exact steps so look it up, but make sure you are selling it to some one who will take care of it. Listening to kids whine about getting a little pink chick makes me sick, and when the parents buy three, I want to faint. Dying chicks is illegeal in some states, so make sure your not breaking any laws.
