I have 2 orp chicks that I was told were splash. One does have a couple of dark spots and the other doesn't have any splash markings. Will these markings show up later? These chicks started out light yellow and now have a bluish tinge. at 3 days old yellow one up front in question at 3 weeks old chick 1that does have a couple of spots chick 2 with no markings also, is it too early to guess genders?
