The other day in Lab Biology (Science) we were doing an experiment where we put a shell-less egg in some form of liquid. (If you put an egg in vinegar, the shell comes off leaving the membrane as the only thing protecting the insides). The point of the experiment was to learn about osmosis. Anyways, my teacher said that the reason chicks are yellow, is because the yolk is yellow. And that if scientist injects dye with a needle into the yolk, the chicks hatch out different colors. I didn't agree with this, if it were true then there would be eggs with black, red, gray, etc. yolks. Many other kids didn't believe him either and they said "really?" He (my teacher) said ,"Why would I tell you something if it wasn't true?". This can't be true, is it? Because natural egg yolks (not from a supermarket) are orange.
