I hatched these bantam Welsummers about 4.5 weeks ago. The combs are almost identical, as is body size. I'm curious about differences in chest feathers and hackle colors. I would say from the red breast that this is a pullet on the left. I would say from the black breast that this is a cockerel. "pullet" on left. "cockerel" on right. Anyone have experience with these, or other partridge colored birds?
