Hello! One of my hens, Elsa, hatched four eggs several days ago. 2 are black sex link pullets, 1 is buff orp/Easter egger cross and the 4th is the mystery chick. It is either BO/BO or BO/RIR (or production red). My RIR'S were sold with that name but after learning more about chickens, they look like production reds. So my question is, what does a BO/BO or BO/RIR chick look like? Here is the photo. The little chick on the far left with brownish face is in question. It also has a faint black spot on its head.
