First two are similar to how columbians start out. Third looks similar to black or mottled. But its nearly impossible to tell at this age with any certainty. Have to wait till at least 4-5 weeks and post pics again.
That livery is soo different that my blacks in same age.. I cant get good pic of that dark guy xD so I have to wait.. in this gang we have 6 blacks, blue and those 3. Father is black mottled and mothers are splash, black and white..but I can't tell what genes they have cause i bought those in another "farm".. ****, Now I can only wait xD
