When we first got out chicks from Cackle Hatchery...the 5 Doms that I ordered ( as pullets ) all had a blue spot on top of the head. We just thought it was some sort of ink applied to them as markers to tell them apart from other chicks....but now I am wondering if it wasnt a natural marking on them?? We keep trying to call Cackle Hatchery to ask them about it and the line is always busy or the # is out of order ! So thought I might ask anyone else who ordered any Doms from them? Also one on my Americana chicks had an orange spot on its head. I did order one of them to be a roo...so we figured his head was marked as well?? Just wondered if someone can clear up my confusion about if they mark the heads of chicks with a mark for ID'ing purposes? Thanks!
