Yes if you look closely at this ones head you see a puff of hair. All my Easter Eggers have this that I got from Tractor Supply - they get them from Hoovers Hatchery.
No Hoovers does not send a extra chick. My guess is there was a mix up somewhere and the hatchery sent you the wrong breed.
It is also not possible for Lavender Orpington or Barred Rock hens to lay green/blue eggs. :)
If I seen the chicken I probably would be able to tell. I have almost owned...
