When I was a kid in Iowa it was traditional for your Dad to bring home a dyed chick or baby rabbit on Easter as a gift for the children. This was all fine but the dye disappeared in not too long a time and all you had was a growing rabbit or chicken. Many of these animals met an untimely demise by being simply turned loose to fend for themselves after they were no longer "cute."
I am not sure if this is something that was just a local tradition or more widespread but I doubt you would see it today, and that is probably a good thing. It really was kind of a cruel practice.
