Hi I hatched some silkie chicks from bought eggs and I don’t know what color is one of the chicks. I thought it was blue but it has more of a brown undertone. I can’t really find this color online. Also it was completely white when it hatched.
Could be exactly that—blue with a brown undertone. It's not exactly standard or encouraged, but it does happen, especially when there are gold modifiers (genetic) present, or the chicken is exposed to a lot of sunlight (bronzing).
