the black/white chick and the red chick on the left are roosters. the red chick in the middle looks to have a single comb, but the male has a pea comb. its possible red/ee crosses, Ive seen people cross 2 differnt breeds and call the chicks pure (like leghorn+ RIR = leghorn)??
did they hatch them, or buy them. If they hatched them from thier birds, ask if they will send pics of the parents.
