Colored Chicks Got Dye Injection While in Eggs

I’ve always thought that 1) buying baby chicks - cute as they are - for little children’s transitory enjoyment on Easter is kind of cruel and 2) colored chicks get to be that way because they are sprayed with dye after they are hatched.

I don’t know if you agree with me or not on point number one, but I guess I was wrong on the second part: chicks can actually get colored by injection of dyes a couple of hours before hatching time!
